             Introns, self-excising ribozymes, can become a useful tool to create in vivo protein fusions of BioBrick parts. To make this possible, intron sequences are used to flank non-protein parts embedded in coding sequences. An intron sequence with an embedded recombination site is capable of in vivo insertion of a compatible protein fusion part. As an example, a GFP-fusion was created with an intervening lox site that is removed from the final protein using the intron to form a fully functional GFP protein. In vivo protein fusions can be applied to a larger number of modular systems to make complicated expression systems, such as synthetic antibodies or plants capable of Cry-toxin domain shuffling.

<br>The goal of Waterloo's 2011 iGEM project is to implement self-excising ribozymes (introns) as biobricks. But first, what are self-excising ribozymes? Ribozymes are ribonucleic acid (RNA) enzymes and enzymes are reaction catalysts. So ribozymes are just RNA sequences that catalyze a (trans-esterification) reaction to remove itself from the rest of the RNA sequence. Essentially these are considered introns, which are intragenic regions spliced from mRNA to produce mature RNA with a continuous exon (coding region) sequence. Self-excising introns/ribozymes consist of type I and II introns. They are considered self-splicing because they do not require proteins to intitialize the reaction. Therefore, by understanding the sequences and structure of these self-excising introns and making them useable, we can use them as tools to make other experiments easier.</br>

This design provides a reasonable basis to implement in vivo applications involving RNA level regulatory sequences such as recombination sites. Since recombination sites can interrupt the functional production of a protein, the incorporated ribozyme portions can remove them before the translation phase of gene expression. Functional synthetic antibodies and plants capable of producing domain-shuffled Cry toxins are possible applications. This experimental investigation is a novel tool for producing a wide variety of these compounds with a supplementary regulation step.

This design provides a reasonable basis to implement in vivo applications involving RNA level regulatory sequences. The fusion proteins produced surpass strictly what is coded in the DNA. As a result of incorporating ribozyme segments in between two halves of the protein coded in the DNA construct, a regulatory sequence (such as a recombination site) could be included. Since recombination sites can interrupt the functional production of a protein if translated fully (resulting in excess amino acids in the polypeptide), the incorporated ribozyme portions remove them before the translation phase of gene expression so that a functional protein is produced. For example, Cry proteins, which account for the insecticidal activity (toxicity) of <i>Bacillus thuringiensis</i>, could be the fusion protein produced for a particular insecticide. Using our experimental design, the sequence containing the code for the Cry protein (at the DNA stage) is split by ribozyme segments containing a recombination site. In this case, the recombination site is the regulatory sequence that will be removed once transcribed into RNA. At the DNA level, recombination (shuffling) will occur, exchanging DNA strand segments. Therefore, when the shuffled DNA sequence is transcribed into RNA, the recombination site is spliced out of the sequence with the ribozymes, and the resulting RNA code is different than that of the un-shuffled code. Consequently, the translated Cry protein is different. This system would oppose pesticide resistance among the target organism.

All group I introns in bacteria have presently been shown to self-splice (with few exceptions) and maintain a conserved secondary structure comprised of a paired element which uses a guanosine (GMP, GDP or GTP) cofactor. Conversely, only a small portion of group II introns have been verified as ribozymes (they are not related to group I introns) and generally have too many regulators to easily work with. It is mainly the structural similarity of these introns that designates them to group II. We will mainly be working with group I introns, such as the phage twort.ORF143.

Group I introns contain a conserved core region consisting of two helical domains (P4–P6 and P3–P7). Recent studies have demonstrated that the elements required for catalysis are mostly in the P3 to P7 domain. They are ribozymes that consecutively catalyze two trans-esterification reactions that remove themselves from the precursor RNA and ligate the flanking exons. They consist of a universally conserved core region and subgroup-specific peripheral regions, which are not essential for catalysis but are known to cause a reduction in catalytic efficiency if removed. To compensate for this, a high concentration of magnesium ions, spermidine or other chemicals that stabilize RNA structures can be added. Thus, the peripheral regions likely stabilize the structure of the conserved core region, which is essential for catalysis.

The secondary structures, such as P6, formed by group I introns facilitates base pairing between the 5' end of the intron and the 3' end of the exon, as well as generates an internal guide sequence. Additionally, there is a pocket produced to encourage binding of the Guanosine cofactor. The Guanine nucleotide is placed on the first nucleotide of the intron. The 3'OH of Guanosine group nucleophilically attacks and cleaves the bond between the last nucleotide of the first exon and the first nucleotide of the 5' end of the intron; concurrently, trans-esterification occurs between the 3'OH and the 5'phosphorous from the 5' end of the intron. Subsequent conformational rearrangements ensure that the 3'OH of the first exon is placed in proximity of the 3' splice site. In this way, further trans-esterification reactions and splicing occurs.</br>

<br><h4 style="color:#0077be">Fusion Proteins</h4>
+
<br><h4 style="color:#0077be">1.3 Fusion Proteins</h4>
Fusion proteins are combined forms of smaller protein subunits and are normally constructed at the DNA level by ligating portions of coding regions. A simple construction of traditional fusion protein involves inserting the target gene into a region of the cloned host gene. However, the subsequent project design, in its simple construction, interrupts the cloned protein with ribozyme sequences flanking a stop codon. The method proposed deals with excision and ligation at the RNA level, therefore, the unaltered DNA sequence does not code for a functional protein.

The method proposed deals with excision and ligation at the RNA level, therefore, the unaltered DNA sequence does not code for a functional protein.
The ligation of protein coding sequences can create functional fusion proteins for many applications including antibody or pesticide production; however, this method of production is limited to producing the same fusion protein each time since the sequence is not modified in between the transcription and translation phases of gene expression. One disadvantage of this is the resultant resistance of a pathogen to antibodies or a target organism to pesticides. For example, a specific pesticide (Cry toxin) may eventually not be effective to its target plant if subsequent plant generations inhibit its uptake, overproduce the sensitive antigen protein so that normal cellular function persists, reduce the ability of this protein to bind to the pesticide or metabolically inactivates the herbicide. Similar mechanisms contribute to antibiotic resistance. Any resistant organisms will inevitably prevail in subsequent generations. Recombination sites could potentially be incorporated into the subsequent project design to circumvent some of the difficulties with traditional fusion proteins as a result of host resistance. However, recombination sites may interrupt the functional fusion protein from forming. Ribozyme segments at the RNA regulation level can potentially remove disrupting sequence after such shuffling occurs. Therefore, the intervening sequence maintains its DNA level functionality but is removed when no longer needed at the RNA level. Fusion protein design focused on the DNA level does not have this dynamic regulation. </br>

In bacteriophage P1 exists the cre enzyme and recognition sites called lox P sites. This viral recombination system functions to excise a particular DNA sequence by flanking lox P sites and introduce the cre enzyme when the target is to be excised. The cre enzyme both cuts at the lox P site and ligates the remaining sequences together. The excised DNA is then degraded. This is similar to our project design; however, instead of requiring the addition of an enzyme at the desired excision time, the self-excising nature of ribozymes automatically functions during the normal process of gene expression (RNA level). </br>

As per RFC 53 convention, enzyme digestions are followed in the particular order outlined below. The standard procedure makes this technique reproducible, therefore, more easily extrapolated to other applications. Compared to other protein fusion methods, this design facilitates additional regulation within necessary guidelines. However, the embedded post-transcriptional modification in this design is a complication to consider in simpler designs where regulation at this level is not necessary. As such, unnecessary bulk in plasmid vectors is known to add to metabolic load.

The above-mentioned methods are considered to be, although fairly reliable, extremely slow. Plating and sensitivity testing are time-consuming processes, which put the previously-mentioned techniques at a minimum delay of 20 to 24 hrs (Warren et al., 2004.) The quickest method available for the detection of Methicillin-resistant Staphylococcus aureus is a PCR assay. Unfortunately, PCR assays are very expensive as compared to other techniques. The cost of some PCR assays (including reagents and technicians’ time) may be approximately $9 CAD per test if done in-house, and around $40 CAD if not (Mahony et al., 2004.) PCR involves the use of primers, which will recognize a sequence particular for MRSA and amplify it, producing a visible fluorescence –detectable result during the amplification stage (Elsayed et al., 2003.) While various testing facilities may use different genes limited to S. aureus, the most commonly used sequences for MRSA detection through PCR are the mecA (responsible for methiciilin resistance) and nuc (S. aureus species-specific marker) genes (Elsayed et al., 2003.) The two methods described below reveal differentiating ways of

The broth PCR technique has been tested to give 93.3% sensitivity, 89.6% specificity, 31.8% positive predictive value, and 99.6% negative predictive value. As the percentage reliability of negative results is very high, especially as compared to that of the positive predictive value, the application of the broth-PCR method will be able to report the negative samples on the morning after testing. This will, in the long run, save as much as 84.9% of the cost and labor which is associated with the necessity of further testing (Fang and Hedin, 2003).

The IDI (Infectio Diagnostic Inc) nasal swab method provides an assay, which completely removes the need for inoculation in liquid or solid media. The assay allows for the performance of PCR directly from a nasal swab sample, using reagents and methods provided by the manufacturer (Infectio Diagnostic Inc). While sample preparation differentiates, PCR methodology applied is quite similar to the one described in section 2.2.1 above. There are, however, distinct differences between the results produced by the two methods. For one, the IDI-MRSA detection method can be complete in as little as 1.5hrs post sample collection, versus next day with the above-mentioned method, and at least 24hrs with the plating methods. As well, The IDI-MRSA provides 91.7% sensitivity, 93.5% specificity, 82.5% positive predictive value, and 97.1% negative predictive value when compared to culture-based methods (Warren et al, 2004.)

As could be noted, there are not many methods available for the detecting of this pathogenic organism. StaphiScope, iGEM Waterloo’s 2010 project, has been designed as a supplement to the methods described above. This diagnostic tool has the goal of sensing and reporting for the presence of S. aureus populations in an area of interest (e.g., a wound) prior to virulence. It will do so faster than any of the described plating methods, and at a lower price. The method relies very heavily on the quorum sensing capabilities of Staphylococcus aureus.

<br><h4 style="color:#0077be">3.1 QUORUM SENSING: WHAT IS IT AND WHY IS IT SO IMPORTANT?</h4>
+
   
   
<br><p>
<br><p>
-
Quorum sensing is defined as “the communication mechanism that enables bacteria to make collective decisions” (Boyen et al., 2009.) This mechanism involves the release of signaling molecules to the cell’s exterior. In gram-positive bacteria such as S. aureus, these signaling molecules are referred to as auto-inducing peptides (AIPs). The signaling molecules could then be detected by special receptors on other bacteria (not necessarily of the same strain) and give feedback in regards to the population density at the site. Bacteria rely on quorum sensing in order to thrive as a population. Most importantly, however, at certain critical concentrations of the AIPs, the bacterial populations make a collective decision to, for example, initiate virulence (Boyen et al., 2009.)
+
Although completion of a preliminary version of the final construct was achieved, lack of GFP fluorescence proved suspicion of questionable band placements during second and third stage electrophoresis. Final diagnostic digestion reaction confirmed abnormalities from designed constructs. Testing via digestion was completed for every intermediate, control and final constructs. Consequently, BBa_K576003, K576004, K576005, and K576006 were the only parts able to be confirmed. All the other intermediates and constructs have questionable band location which disrupted final construct fluorescence.

</p>
+
-
<br><p>
+
-
This year, the UW iGEM team is attempting to listen in on the quorum sensing “conversations” of S. aureus, by engineering E. coli to receive the AIP signaling molecule mentioned above. Through a signal amplifier, E. coli would be able to detect the presence of S. aureus at very low concentrations, and prior to the bacteria having the chance to become virulent.

<b>Figure 10:</b> shows the diagnostic digestion from September 16, 2011: All subclones shown to be correct, however, positive control not correct. Relative placement of GFPs and INTS required further verification and showed incorrect placement. This accounts for lack of fluorescence in final stage.</div><br>

The purpose of StaphiScope is to provide the option of speeding up some of the methods mentioned above, without compromising their reliability. It will be a particularly useful tool in speeding up the conventional methods of serial plating. In particular, the plating method described above requires that samples first be plated onto either Mannitol  Salt Agar in order to obtain yellow colonies, or Blood Agar to obtain zones of clearance. This will aid in picking out Staphilococcus aureus apart from other species which may have grown. Only after this initial growth can we plate on antibiotic plates containing β-lactam class of antibiotics (methicilin, penicillin and a few others). This would normally take up another, at the very least, 18-24 hours. Using StaphiScope, we could speed up the first step of this process, by picking out the Staphilococcus aureus from all other species without the requirement of growing them up on solid media overnight first. With StaphiScope, the bacterial population from the samples would be grown into liquid culture, and the presence of RFP will be evaluated. The following will be involved in using the StaphiScope method commercially:
+
The above electrophoresis picture describes the resultant bands from the diagnostic digestion. Although bands 5, 6 and 7 (sub clones) have been confirmed, the adjacent positive control (band 8) and all GFP and intron digestions are not consistent with the expected patterns. The GFP-INT and GFP-INT-lox constructions (bands 9, 10 and 11) have been verified as inaccurate. The questionable placements of these bands indicate that the cut sites, thus the fragment length and containing sequence, do not match the planned construction. Therefore, it is not likely that they contain functional GFP, introns or lox, which would result in a lack of fluorescence in the final stage of construction. Further testing to reconstruct the contaminated clones is necessary for the functional final product; however, lab work has stopped due to time constraint. A diagnostic digestion at each step is recommended to circumvent any similar issues upon the continuation of this project.

<br><h3 style="color:#0077be">3.0 PRACTICAL APPLICATION </h3>  
-
<br>3.Inoculate sample from patient into liquid media containing StaphiScope and place at 37°C for 3 – 4 hrs. In our experience this is sufficient to show color of RFP is it has been activated. In addition, it would be useful to spin the cells down through a centrifuge (2 min at 13, 000 rpm). This would  bring the cells to the bottom, allowing us to see the red color expressed more clearly.

<br>4.Upon positive result (red color produced), the cells could now undergo either plating on media containing the methicillin class of antibiotics, or a PCR-detection method using nuc/mecA genes (as described in section 2.2.1)

</p>
+
-
<br><p>
+

This method would bring the time consumption demands down to a few hours, as opposed to at the very least, a day. As well, less media would be used in the process. Finally, it is much cheaper than the faster methods such as PCR.
+
-
</p>
+
<br><p>
<br><p>
-
It is possible to initially inoculate the sample from the patient into liquid broth containing samples of the methicillin class of antibiotics. The expression of RFP in this case would mean that MRSA are present. This direct method of detection could shorten the test to 3-4hrs in length. However, this may lead to false positive results, as it is possible for other bacteria to release AIP as well, activating the StaphiScope.
+
The biggest advantage of the ribozyme project is the ability to create in vivo protein fusions. These can then be applied to a larger number of modular systems that can be used to make complicated expression systems. One such system is the creation synthetic antibodies. If protein sequences are flanked by intron sequences and then set up along the same stretch of DNA, different combinations of fusion proteins will be created based on how the intron excision occurs. Another system where the ribozyme project can be applied is DNA shuffling experiments. The Cry toxin is used as an effective biopesticide, however for now it has a very small range of insects that it effects. The ways to increase its range would be to change the structure of one of the vital domains so that it is able to recognize a wider spectrum of receptors in the host mid gut cell. To create different variations of this domains an in vivo DNA shuffling experiments using the ribozymes could be carried out.

<p>Waterloo’s 2010 iGEM project, "Staphiscope", utilized amplifier parts developed by Cambridge in 2009 to detect low levels of Staph Aureus.

An additional design involved the addition of a generator part. This would have allowed E.coli to produce its own AIP, as a means for testing the response without worrying about permeability into the periplasm.  This design was completed but could not  be tested due to time constrains. As well, no amplifier was added in the final construct. Below is a discussion of the major components of StaphiScope.

<br><h5 style="color:#0077be">3.3.1 COMPONENT #1: FEP A PERMEABILITY DEVICE</h5>
+
<p>In order to characterize the amplifiers, a parameter scan was undertaken to find promoter-independent Hill parameters of each amplifier, consistent with data of full system. However, empirical verification of our results was lacking. This year, we sought to obtain this data, which (in conjunction with Cambridge data and model), would allow us to find Hill parameters for each amplifier.

As S. aureus releases AIP in order to initiate any kind of quorum sensing, it is important that Escherichia coli will be able to receive and properly identify this signal. As E. coli is a gram-negative bacterium (contains an additional outer membrane), an issue arises of AIP not being able to get through this extra layer. This is why the iGEM team was forced to use FepA as part of the plasmid construct. FepA is an outer membrane permeability device, which will allow for AIP (the quorum sensing signaling molecule which will come from S. aureus) to get through the outer membrane of the gram-negative E. coli. The permeability device comes with its own promoter, on which we will rely for optimal expression.

+
-
<br><h5 style="color:#0077be">3.3.2 COMPONENT #2: AIP SENSOR</h5>
+
-
+
-
<br><p>
+
-
It is important that AIP does indeed make it past the outer membrane of E. coli, as this is crucial to turning on the sensor and reporter functions of the StaphiScope. The AIP sensor function will allow E. coli to “listen in” on the quorum sensing conversations of the S. aureus. The BioBrick is modeled after the agr (accessory gene regulator) quorum sensing system present in S. aureus. AIP (from same cell or from another cell producing the peptide) binds AgrC (a histidine kinase). This, in turn, allows for phosphotransfer to AgrA and subsequently, through activation of transcription, more AIP is produced, amplifying the signal. It is a loop (Atkinson and Williams, 2009.) This is part of the mechanism which allows the bacteria to be aware of the concentration of its own strain in the infected area, subsequently leading to a “collective decision” such as expressing virulence. Please refer to Figure 2 for a visual display of the previously mentioned.

<p>To allow for comparison of data, we used the same model as <a href="https://2009.igem.org/Team:Cambridge/Modelling">Cambridge in 2009</a>.</p><br>
-
<br><p>
+
-
This BioBrick will serve the purpose of further amplifying the AIP signal obtained by E. coli, and thus, allowing it to “sense” S. aureus, before S. aureus has had the chance to produce a high enough concentration of the quorum sensing signal to initiate a response. In other words, E.coli would be able to, through amplification, “sense” S. aureus before S. aureus has had the chance to sense itself. Unfortunately, there was insufficient time for proper research to be done on this, and so, the final construct lacks an amplifier. The amplifier is not a necessary part, but simply an assurance that the signal will be received through over-amplification.

-
<br><h5 style="color:#0077be">3.3.4 COMPONENT #4: RFP REPORTER</h5>
+
-
+
-
<br><p>
+
-
This RFP BioBrick will produce a red-fluorescence signal proportional to the AIP concentration E. coli senses. This way, not only would one be able to tell that S. aureus is present, they would also be able to quantitatively compare samples to see where the infection has spread further. This would mean being able to decide whom to treat first, in the worst case scenario.

-
</p>
+
-
<br><h5 style="color:#0077be">3.3.5 COMPONENT #5: AIP GENERATOR; PERIPLASM TEST.</h5>
+
<p>In this model, araC represses the pBAD promoter in the absence of the inducer, arabinose. When arabinose is present, it binds to araC, preventing repression of the promoter and allowing transcription of reporter (GFP). This situation is modelled by a Hill function; we seek the Hill parameters of this function.</p><br>
-
<br><p>
+
<p>Thus, when AraC/pBAD system is induced with arabinose, we expect to see a steady increase of fluorescence from a low level, followed by a plateau of fluorescence at steady state.
-
The purpose of this construct will be to check the sensor-reporter system. The alternative construct contains AIP Generator for self-induction and no permeability device to facilitate accumulation of AIP in the periplasm. The system would essentially product its own AIP, thus showing activity of sensor-reporter system before final tests in presence of S. aureus.

+
<h3 style="color:#0077be">Method</h3><p>To measure fluorescence, we closely followed the assay described in the paper <a href="http://www.jbioleng.org/content/3/1/4">"Measuring the activity of BioBrick promoters using an in vivo reference standard"</a>, in the section "Assay of Promoter Collections".</p><br>
-
<br><p>
+
<p>Three cultures were grown overnight at 37 degrees Celsius with spinning at 200 rpm: untransformed BW27783, BW27783 containing BBa_I0500, and BW27783 containing BBa_I20260. These were then diluted 1:100 and regrown for roughly 4 hours under the same conditions. They were then diluted to an OD between 0.05 and 0.09, and regrown for 1 hour, again under the same conditions.</p><br>
-
As a supplement to the following information, please refer to the construction tree presented in Figure 3 below.

-
</p>
+
<p>After this, the cultures were diluted into a 96-well plate at 8 different concentrations of inducer (arabinose), ranging from 0 to 6.4 uM. The plate was then incubated in a Wallac Victor3 multi-well fluorimeter at 37 degrees Celsius, and repeating measurements of absorbance and fluorescence were taken at 10 minute intervals, with shaking after each measurement. Untransformed BW27783, at each concentration of arabinose, was used to measure background fluorescence, and wells containing only broth were included to measure background absorbance. The machine settings used were identical to those described in the paper referenced above.</p><br>
-
<br><p style="text-align:center">
+
<p>With this data, we aimed to calculate the steady-state per-cell GFP concentration during log-phase growth, for both BBa_I0500 and BBa_I20260 (measurement kit for the standard promoter, J23101). The ratio of these values would then characterize the strength of the AraC/pBAD promoter in units of RPU. The justification for this approach can be found in the supplemental material of the paper referenced above.

<h3 style="color:#0077be">Results</h3><p>
 +
The results of the experiment were anomalous, and considered too unreliable to be conclusive. There was no clear relationship between cell fluorescence and inducer concentration.</p><br>
 +
<p>The fluorescence curve did not qualitatively match the predictions of the model; across all concentrations, and for each of the 3 cultures, we observed a high initial fluorescence, with a rapid drop to a lower steady state value. For each culture, this drop in fluorescence aligned well with the growth curve.</p><br>
 +
<p>In addition, the untransformed BW27783 cells exhibited consistently higher fluorescence than cells containing BBa_I0500, which was highly anomalous. Because of this, we could not reliably use these cells to measure background fluorescence.</p><br>
 +
<p>Below, a sample graph of Total Fluorescence is shown for each of the 3 cultures. These are curves of the total fluorescence for each culture, averaged over 3 replicates for each culture.

<h3 style="color:#0077be">Discussion</h3><p>It is believed that an error in our strain of BW27783 is most likely responsible for the anomalous qualitative features of our data. This is because for each concentration of inducer, the untransformed BW27783 cells exhibit a fluorescence curve highly similar to that of BW27783 containing BBa_I0500, and yet the untransformed cells should not be expressing GFP.</p><br>
-
<br/><h4 style="color:#0077be">3.5 THE QUANTIFICATION INITIATIVE</h4>
+
<p>Prior to the measurement assay, BW27783 cells transformed with BBa_I0500 were plated and examined for fluorescence, both with and without the presence of inducer. The uninduced cells were not found to fluoresce, while the induced cells did fluoresce. The fluorescing cultures were used to make the frozen stock of BBa_I0500 which was used in the measurement assay. This indicates that our untransformed BW27783 should not fluoresce without the presence of inducer. Furthermore, the untransformed BW27783 cells used in the measurement assay were at no point prior to the assay exposed to arabinose.</p><br>
-
<br/><p>
+
<p>To explain the fluorescence of the untransformed BW27783 in the measurement assay, it is speculated that our strain of BW27783 exhibits a rapid production of GFP in response to even low concentrations of inducer. Experimental error is also a likely source of inaccuracy in the data, although the qualitative features described were consistent across 3 trials of the experiment. Research into these results is still ongoing.
-
Characterization of certain parts, functioning as signal amplifiers, was done by the iGEM Team Cambridge, which designed them, in terms of arabinose as an input signal. The arabinose sensing system consists of promoter pBAD and it respective repressor AraC. The BioBrick part BBa_I0500 contains both of those components in one part, while BBa_I13453 and BBa_I13458 are similar to BBa_I0500 split into two components: pBAD and AraC respectively. In order to retrieve the data about Team Cambridge’s parts, the modeling division of iGEM team Waterloo 2010 requested characterization of pBAD in relative promoter units (RPUs). The article by Kelly et al. (2009, Measuring the activity of BioBrick promoters using in vivo reference standard) describes the issue of great deviations involved with measuring biological systems due to too many factors to account for. The proposed solution is to measure in reference to a standard: the promoter BBa_J23101. The proposed vector for both the measured part and the standard is pSB3K3 (low copy number kanamycin resistant BioBrick plasmid) with green fluorescent protein gene as reporter. Inspired by swappable promoter construct BBa_J61002 similar construct with J23101 in place of swappable promoter element was derived from pSB3K3, the BBa_K359201.

The purpose of UW iGEM Outreach has always been and will continue to be the connection between our community and us. To help build a better understanding of synthetic biology, how it has affected the world around us and to create a basic, fundamental knowledge of the subject that can be incorporated into the way we see things. That perspective can be positive or negative, but we aim to provide the baseline knowledge required that will allow our community members to form a fact-based opinion.<br/><br/>

This year, UW iGEM: Outreach focused on designing and running workshops targeted at schoolchildren. We hoped to share our love and passion for biology with tomorrow's future scientists and engineers. We plan to continue building on what we currently have and to eventually develop a complete syllabus for all grade levels. These workshops will be available for download for other educators and enthusiasts interested in their own outreach.<br/><br/>

RFP (BBa_E1010) will be used instead of GFP due to consistent failure to express GFP (BBa_E0040) reported by Waterloo iGEM teams from previous years. The fluorimetric assay can be performed on a fluorescent protein with the use of flow cytometer or microplate reader. The two approaches focus on different aspects of the retrievable data. Flow cytometry acquires data on individual cells, however each new concentration of input and time point requires individual assay. Incubating fluorescence-capable plate reader allows to acquire many time and concentration points overnight or even several nights, and is thus preferable. Checking back on the QC sequencing data for I0500 it was discovered that the integrity of the part in the distribution available was not succesfully confirmed by sequencing, which explains failure of RFP expression with this part.

The AIP molecule utilized by S. aureus as part of its quorum sensing mechanism is part of a group of 4 classes of signaling molecules, all with the ability to cross inhibit each other’s activity. It could be speculated that, if present at the same time, they would slowly inhibit the signal transmission between members of the same infection site, and thus prevent infection. Thus, it would be recommended that, after the construction of the StaphiScope, an extension be added to the project, where within Escherichia coli is integrated the function to produce a signal molecule of the cross-inhibitory group (Atkinson and Williams, 2009)

<h3 style="color:#0077be">1.0 INTRODUCTION</h3>
+
-
<p>Since the Staphiscope project aims to detect S. aureus at low concentrations, it's important to determine how sensitive the system will be so that it can be adjusted to detect S. aureus at clinically-relevant concentrations. A detector that triggers at too low a concentration may display false positives, while one that triggers at too high a concentration may not give a positive when it should. To achieve the best sensitivity, numerical characterization for the Cambridge's 2009 sensitivity tuners needs to be obtained <i>independent of the promoter used</i>, in order to be combined with models for the AIP detection system and yield a predictive numerical model for Staphiscope. Work toward these ends is ongoing.</p><br>

<h3 style="color:#0077be">2.0 BACKGROUND</h3><p>
+
<h3 style="color:#0077be">Events</h3><br/>
-
The sensitivity of Staphiscope may depend on various factors. For now, analysis has been restricted to just one factor: the choice of part used for the amplifier component of the system. The amplifier will be chosen from one of the 15 amplifiers submitted to the parts registry by Cambridge in 2009. Each amplifier responds uniquely to a given input signal, differing from the others with respect to its activation threshold (amoung a few other parameters less crucial to our analysis). Our goal is to determine which amplifier has an activation threshold in the correct range for the detection of S. aureus in relevant concentrations.</p><br><p>
+
We were also fortunate enough this year to have been given the opportunity to run our workshops at two different outreach events, both of which were on a grand  scale. Now, we'd like to share our experiences with you.<br /><br />
 +
<h3 style="color:#0077be">Grade 12 Outreach Workshop: March 25th, 2011</h3><br />
 +
The first was an organized Grade 12 workshop aimed at biology students to gain a better understanding of synthetic biology, the industries it has been affecting, career prospects as well as two hands-on activities. Over the planning span of 3 months, this event was organized in close accordance with the Kitchener-Waterloo school board and with the Marketing and Recruitment Co-ordinator for Science at the University of Waterloo. Through the creation of a brochure and meeting with individuals from the school board we had sent out an invitation all across the district for students to come in for our event. Eventually we had gotten more than 85 students to attend, which was great as it was the first time we had implemented this idea. <br /><br />
 +
The next step had then been to recruit interested volunteers for the event so we could have our own students give a helping hand and who shared the same passion of sharing knowledge as we did. In order to facilitate this we had sent out emails, gone to various lectures and talked to students all over campus to get them involved. After recruiting 12 volunteers the brainstorming process had begun. We had wanted to have an interactive workshop where students were not just listening to us talk, but were actually involved in a stimulating activity that they could be excited about.
 +
The first part of our presentation looked into what was synthetic biology, what were Genetically Modified Organisms (GMOs) and what were the positives and negatives of them. Once that was through we started the first event.
 +
The first event we had was to talk about our very own Canadian genetically enhanced Yorkshire pig called the EnviroPig™. It has the capability to digest plant phosphate more efficiently than traditional Yorkshire pigs, which do not contain the enzyme to break it down, phytase. This gene can be found in E.coli which had been inserted into a pig embryo to allow it to produce phytase in its salivary glands. This is a real technology in Canada and is currently a very hot topic of debate among many citizens, so we thought it would be ideal to introduce students to the world of biotechnology right in their very own backyards. Once students had been exposed to the information, we had given them a package which we had compiled giving the positives and negatives of societal, technological, ethical, environmental and economical issues. <br /><br />
 +
  Of course, it did not end there! Students were then put into groups of 5 and as mentioned above, one of the key goals of UW iGEM Outreach is to allow members of our community to make informed decisions based on facts. Supplied with markers and paper students were to give a 1-2 minute presentation on why they did/did not believe that the EnviroPig™ should continue receiving funding from the government of Canada. The best and most convincing presentation won- we had great discussions from the negative aspects to positive aspects to even a compiled rap song about the EnviroPig™! <br /><br />

Empirical characterization of the response curves of each amplifier was carried out by Cambridge. However, in Cambridge's system the amplifiers were under control of the the pBAD promoter, which is not the case in Staphiscope. Therefore, the data gathered by Cambridge is not directly applicable to our system, since in general the response curve of each amplifier will be different under different promoters.</p>
+

-
<br><p>
+
-
To obtain a numerical characterization of each amplifier, independent of promoter choice, we are undertaking the task of "reverse engineering" Cambridge's data to extract the parameters describing the amplifiers. A more detailed explanation of our approach first requires a description of the mathematical models relevant to this system.
+
-
</p>
+
-
<br>
+
-
<h3 style="color:#0077be">3.0 SYSTEM MODEL</h3><p>
+
-
The parts characterized by Cambridge consist of a detector (the pBAD/AraC promoter) and one of the fifteen amplifiers. To obtain a mathematical description of the entire system, Cambridge used the following equations to describe the input/output response of these individual components.</p>
+
-
<br><p>
+
-
<img src="https://static.igem.org/mediawiki/2010/8/8d/Waterloo2010Modelling_Table1.PNG" alt="Table of equations.">
+
-
</p><br><p>
+
-
The <a href="https://2009.igem.org/Team:Cambridge/Modelling">Cambridge 2009 modelling page</a> develops these equations in more detail.</p>
+
-
<p>
+
-
When these individual component models are strung together, the resulting model of the entire system has a sigmoidal shape. This means the response curve for the entire system can be fit to a Hill function, which is of the form
+
-
<img src="https://static.igem.org/mediawiki/2010/b/b2/Hillfunction.gif" alt="(general hill function equation)">.</p><br><p>
+
-
Note that 4 parameters are required to specify the response curve: increase in rate, basal rate, switch point, and Hill coefficient. These parameters need to be determined empirically, with the exception of the Hill coefficient, which we assume is equal to 2.
+
After the first event we continued on with our presentation. Here we discussed current industries that had been affected by synthetic biology. This incorporated the pharmaceutical and biofuels industries specifically. We discussed how pharmaceuticals had incorporated an aspect known as biosynthesis where they could customize and fine-tune certain pathways using standardized parts in order to provide efficient and precise drug delivery systems. In biofuels we talked about first and second generation biofuels and how the use of synthetic biology has the ability to create a ‘superbug’ to look for corresponding metabolic pathways for yielding ideal results. After this we did the second activity. <br /><br />
-
</p><br><p>
+
The second event that had been implemented was to incorporate what we do in our labs, outside of the lab. Essentially, we wanted to introduce the idea of synthetic biology to students and how it was an extension of what we knew as genetic engineering and consisted of students not just from science but from math, engineering and computer science. The activity called, ‘Design Your Own Pathway’ gave a series of scenarios we had given students with a library of BioBricks to create a certain pathway. Progressively each scenario was harder, more complicated and required the use of multiple BioBricks. The BioBricks that we had used were from the library and were real parts. Essentially this was to enable students to have a feel of how we have a ‘mix and match’ concept when it comes to synthetic biology. The activity had been set up as a relay race, where students in the same teams as the previous activity had to race each other to finish all scenarios. The activity and concept had been such a success that after the workshop teachers had asked to use our activity in their own classrooms.  
-
The detector and amplifier also each have the form of a Hill function, but of course each has its own set of parameters which will differ from the Hill parameters of the overall system.

<h3 style="color:#0077be">4.0 EXTRACTING DATA</h3><p>
+
  <div style="text-align: center;"><img src="https://static.igem.org/mediawiki/2011/9/98/Watout3.png" width="350" height="270"><img src="https://static.igem.org/mediawiki/2011/7/7c/Watout4.png" width="350" height="270"><br/><br/></div>
-
Ultimately we seek a numerical characterization of the amplifier part alone. Since we know its response curve has the form of a Hill function, we need only find its four Hill parameters. The following table summarizes the known and desired data.</p>
+
-
<br><p>
+
-

+
-
</p><br><p>
+
-
If all the parameters other than the amplifier parameters are known, the model above together with the response curves of the amplifiers is enough information to extract the desired parameters. Explicitly solving the equations above for the amplifier parameters is difficult; instead, MATLAB's curve fitting toolbox will be used to find the parameters which, when combined with the known parameters and inserted into the equations for Cambridge's overall system, matches the empirical data obtained by Cambridge. This process must be repeated for each of the 15 amplifiers.
+
-
</p><br><p>
+
-
Unfortunately, not all the necessary parameters are known. Some were not measured by Cambridge (those in block 1), but can be found in the literature. However, the Hill parameters for the pBAD/AraC promoter are not known, and must be measured. To do this, an experiment is being designed to characterize this promoter in RPU, but has not yet been carried out.</p>

+
-
<br/><p>
+
-
The newness of synthetic biology means that much of the population is not even aware that it exists (see Awareness & Attitudes Study see link at the bottom of this section). Therefore, an important aspect of our outreach efforts is to introduce the topic of synthetic biology and show its potential. We also hope to give people the foundational information that they need in order to understand future scientific developments. This form of outreach will help to improve the scientific literacy of the general population.
+
-
</p>
+
-
<br/><p>
+
-
Another emerging issue is misconceptions held by the general public. In the development of synthetic biology, as with many new technologies, there is still much to learn and discover. As a result, the information made available to the public is often not a comprehensive, accurate picture of synthetic biology.
+
-
</p>
+
-
<br/><p>
+
-
The following are the goals that we hope to achieve through educational outreach:
+
-
<br/>
+
-
<br/> 1.Inform the public about synthetic biology
+
-
<br/> 2.Promote an education in science
+
-
<br/> 3.Showcase opportunities in the field of science
+
-
<br/> 4.Create an enriched science experience for students

-
<br/> 5.Broaden the influence of iGEM

<h3 style="color:#0077be">1.2 The Events</h3>
+
-
<br/><p>
+
-
The method that we have chosen to achieve our goals is science education. This is the avenue most accessible and familiar to us as science students. By participating in events in our community we are able to influence multiple audiences by different means. Our outreach efforts are primarily focused at young students still deciding whether to continue in the field of science, students pursing science education, and the general public. Some of the events facilitated delivering the information on a small scale (in depth discussions with one or two students) while other events necessitated speaking more generally to larger groups. The events fostered synthetic biology awareness and were great learning experiences for our team.

<a href:"http://esq.uwaterloo.ca/">
+
-
Engineering Science Quest
+
-
</a>
+
-
) is a day camp hosted at the University of Waterloo that brings hundreds of curious young minds to Waterloo each year to learn more about science and engineering. We held two different weekly activities for campers of ages 8-9 and 12-14.
+
-
</p>
+
-
<br/><p>
+
-
The activity for children of 8 to 9 years of age involved extracting their own DNA from their cheek cells. It was approximately an hour and a half in length, and involved not only following the outlined procedure, but also, a discussion of synthetic biology, DNA, proteins, enzymes and more. At the end of each activity, the children were allowed to keep a sealed cryovial with their extracted DNA.

</p>
+

The protocol for the activity, as well as the PowerPoint presentation and script associated with it, are available here.
+
-
</p>
+
-
<br/><p>
+
-
The second activity, which involved children 12 to 14 years of age was named “Do We Really Need to Wash Our Hands.” In this activity, the children were asked to swab their own hands (using a sterilized cotton swab) and plate the resulting swab on solid media. They would then wash their hands/use hand sanitizer and swab and plate again. The plates would be left to incubate at 37°C overnight, and the next day, the resulting growth would be presented to the children. As well, they were allowed to swab two other area of their choice, as to see how “dirty” these are. Most chose their own hair, backpack or shoe.
+
-
</p>
+
-
<br/><p>
+
-
Prior to each activity, a PowerPoint presentation discussion bacteria, pathogenicity, hand-washing, DNA and synthetic biology was given to the students. As well, they were provided with a hand-out to aid them in their understanding of the activity. The handout contained step-by-step activity protocol, as well as spaces for hypothesizing and discussion. The PowerPoint presentation, protocol, script, and handout are available here.

We hope that these initiatives will help engage students outside of the classroom and get them excited about science.

Finally, we completed the presentation with a discussion of career paths that students could pursue that did not necessarily involve working in a lab. We wanted students to understand that the world of synthetic biology and biotechnology encompasses the involvement of individuals from multiple backgrounds and can penetrate into many different industries. <br /><br />

<br/><h4  style="color:#0077be">iGEM Ontario (OGEM) Meeting, June 15 2010 at McMaster University</h4>
 
-
<br/><p>
 
-
The second annual OGEM Meeting was held at McMaster University in Hamilton on June 15th, 2010. Members of iGEM teams from University of Waterloo, University of Western Ontario and University of Toronto gathered to discuss the future of a regional synthetic biology community, as well as a regional conference. The day turned over to discussions which centered around creating more communication and support between teams. In addition, the gathering was also an opportunity for teams to get to know one another before heading down to MIT. The meeting was a great success and the second of more regional gatherings to come.
 
-
</p>
 
-
<br/><p>
 
-
As the meeting was held during the annual CSM (Canadian Society for Microbiologists) conference, members were able to attend a series of lectures given by valuable members of the field. As well, iGEM Ontario members were given the opportunity to speak about their projects and promote the idea of iGEM during a poster presentation held along with researchers in the field of microbiology.
 
-
</p>
 
-
<br/><p>
 
-
In the future we hope to see this organization (independent of an individual iGEM team) become an important resource to Ontario iGEM teams and for educating the general public about synthetic biology. We are currently working on an iGEM Ontario website.

<h3 style="color:#0077be">Engineering Science Quest: July-August 2011</h3>
-
On June 23, Waterloo iGEM adviser, Dr. Trevor Charles, held an open public lecture aiming at discussing synthetic biology, its means and aims. During the lecture, the purpose of synthetic biology, its ethical and safety implications well as many other current topics were discussed. At the end, a facilitated panel discussion featuring Andre Masella (Waterloo iGEM team), Dr. Kathryn Plaisance (bio-ethicist), as well as Dr. Maria Trainer (Council of Canadian Academics) answered some of the public’s pending questions regarding synthetic biology. The lecture was a great success, with a large number of attendees of various scientific background. It was part of a series of lectures organized by the University of Waterloo’s Department of Biology, in attempt to increase public awareness of current scientific issues.
+
Founded in 1990, the Engineering Science Quest or ESQ is a not-for-profit program that operates with the goal of exposing children in the Kitchener-Waterloo region to the world of engineering, science and technology through engaging them in a variety of hands-on activities. Promotion is primarily done through workshops in-school but also have satellite programs which reach out to rural and Native communities as well.<br /><br />

<br/><h3 style="color:#0077be">What We Accomplished</h3>
+
This is not the first time that UW iGEM has been involved in ESQ and we are proud to say that our continued involvement has allowed us to develop a standard set of activities which we are pleased to present to kids ranging from Grades 3-6 with more than 100 students. Currently we are also developing ideas for older kids that are similar to our activities from the Outreach workshop we had in March for Grades 10-12 and for even younger kids from Grades 1-2. Through involvement with managers specifically for ESQ this year we were able to have continual workshops every week from July 11th- August 12th, 2011. This was done with the recruitment of volunteers who again shared the same passion as we did in connecting with our community to facilitate that baseline knowledge; to get students introduced or even extend their knowledge on the world of synthetic biology and biotechnology.<br /><br />
-
<br/><p>
+
-
Upon reflection we feel that we have achieved the following goals through our outreach efforts:
+
-
<br/>
+
-
<br/> 1.Introduced synthetic biology to individuals who knew nothing about it
+
-
<br/> 2.Educated multiple audiences on the fundamentals of science such that they will be able to better understand future scientific information and developments
+
-
<br/> 3.Excited young minds about science
+
-
<br/> 4.Strengthened our regional synthetic biology community
+
-
<br/> 5.Communicated the work of other iGEM teams and the benefit and goals of the iGEM competition
+
-
<br/> 6.Increased communication between local synthetic biologists
+
-
<br/> 7.Gained insight and experience into what the public believes about modern science
+
-
<br/> 8.Developed activities and displays to be used and improved upon in the future
+
-
</p>
+
-
<br/>
+
-
<h3 style="color:#0077be">Future Plans</h3>
+
-
<br/><p>
+
-
We plan to continue our outreach efforts in the future. We plan to expand our efforts and continue to educate the public about synthetic biology and share our love of science. In the future our efforts will continue to center around science education. Our profile in our community is increasing as iGEM becomes a familiar group and synthetic biology ceases to sound frightening and gains familiarity. We hope that the Ontario community of iGEM teams will continue to grow and include teams from all across Canada, helping to strengthen the synthetic biology community across the country. As members of the Waterloo iGEM team we are proud to educate multiple audiences and to share our knowledge and passion with the world.

<h3 style="color:#0077be">INTRODUCTION</h3>
+
-
<br><p>
+
-
As synthetic biology expands, as new innovations are made, and pressing world problems are solved, the potential impact synthetic biology will have on the world becomes more evident. Although a primary goal of developers of synthetic biology should be to consider the ethical, societal, safety, environmental, and political impact of the science, we believe that interest should also be paid unto the impact that synthetic biology will have in the business world.
+
-
</p>
+
-
<br><p><b>
+
-
As a group we are most interested in the course of development of synthetic biology in industry; the goal of our project is to try and decipher the path that synthetic biology will forge as it expands in the business world.
+
-
</b></p>
+
-
<br><p>
+
-
Our attempt to answer this question has begun with a comprehensive inquiry into important factors affecting the diffusion of synthetic biology. It is our opinion that before we attempt to make any conclusive statements about the future direction of synthetic biology or the economy as a whole we must have a complete picture of the current landscape of synthetic biology and the markets it could potentially impact.
+
-
</p>
+
-
<br><p>
+
-
This inquiry is intended for use by multiple audiences; particularly scientists and members of business in relevant industries. As scientists it is important to understand the context in which discoveries are made, understanding where world needs lie and how discoveries will impact the world makes for better-informed scientists. Members of the business world should also strive to have an understanding of where the need and rationale for discoveries come from. Although profit is the ultimate endgame a well-informed approach helps to prevent ethical pitfalls and often greater success.
+
-
</p>
+
-
<br><p>
+
-
This analysis looks at both extrinsic and intrinsic factors relating to the development of synthetic biology as a whole. In particular intrinsic factors such as the development of synthetic biology in specific industries (biofuels, pharmaceuticals, and bioremediation) is examined in depth. Important extrinsic factors such as the impact of patenting and open source are also analyzed. With this information we feel we have laid the foundations for a comprehensive inquiry that will allow us to better understand what the expansion of synthetic biology in the business world will resemble.

  The first activity for Grades 3-4 was called, “All About Bacteria: Do You Really Need to Wash Your Hands?” In this activity we introduce kids to the idea of biology, bacteria, synthetic biology, and iGEM. We also introduce them to basic ideas of sanitary techniques and tools used in a standard lab such as petri plates, agar, swabs etc. and how to layout an experiment; what is your hypothesis, results and conclusions? Once we discuss these basic concepts we allow the kids to take a swab of their hand and plate it on half of a petri dish. They then clean their hands with sanitizer and swab the other half of the petri dish. They then receive another petri dish where they can swab other places to find other ‘neat’ bacteria that may be lying around on the floor, counters, door knobs or wherever else they want (except up their nose, in their eyes, ears or mouth!). At this point and throughout the activity, interaction with the kids is key, as they always have stories or thoughts and experiences that are enlightening to share- even to us university students. <br /><br />

<br><h4  style="color:#0077be">What is Open Sourcing?</h4>
+
-
<br><p>
+
-
What differentiates synthetic biology from biotechnology is that it offers the creation of systems or pathways that would not be found naturally in an organism. Synthetic biologists believe in a standardized system of parts similar to that of electrical engineers having standard circuits and components<sup>1</sup>. This is also similar to how LINUX modules have been combined to create different software. This contrasts the closed-parts strategy where developers use such methods as patent protection and secrecy to gain a competitive advantage over others<sup>2</sup>.  
+
-
That is why the Massachusetts Institute of Technology (MIT) has created the initiative for what is known as the “Registry of Standard Biological Parts” where it indexes biological parts that are currently being built. A standard array of modular gene switches or parts that can be found from a common library and can be mixed and matched in various combinations, which is the goal that synthetic biology targets. This is a similar path as what happened twenty years ago when software became standardized and allowed Microsoft to become a monopoly. The issue in the air currently is if this could happen with the synthetic biology industry<sup>3</sup>.
+
-
</p>
+
-
<br><h4 style="color:#0077be">Advantages</h4>
+
Once we explain what incubation is, we allow kids to come in the next day and see all the different types of bacteria that may have grown on their petri plates and come up with conclusions from the results they have seen. We provide them with a record sheet where they are able to write down what they saw such as; morphology, colour, its surface and even elevation. To be able to interact with kids at such a young age and to introduce them to concepts which students are normally exposed to in higher grades, allows them to explore a part of their world that they never knew existed. Building curiosity at a basal level helps us connect with our community and bridge the gap towards making more informed decisions.
-
<br><p>
+
<br /><br />

Open-sourcing has been an idea that has been the basic foundation of synthetic biology throughout the years. Supporters strongly believe in a world where companies and academia will be able to develop and share parts freely for the advancement of the whole field, not just a singular firm or university<sup>4</sup>.
+
The second activity for Grades 5-6 was called, “DNA Extraction from Your Cheeks”. This activity centers around the idea of DNA, where it is found, what it looks like and how every living organism contains very similar genomes, proteins and enzymes. There were four steps to this process, first to collect cheek cells, second to burst cells open to release DNA, third to separate DNA from proteins and debris and finally isolate the concentrated DNA. Kids obtain a cup of Gatorade containing a saline solution and swish the drink in their mouth for about a minute while gently chewing on their cheek cells. Then detergent is added to the test tube and meat tenderizer is added and the tube is inverted gently a couple of times. Cold rubbing alcohol is then added with a pipette which should allow the DNA to be visible. Then kids  transfer the DNA into a PCR tube where they can hang it on a string to make a really neat necklace. <br /><br />

A term that is used commonly in this industry is called network effects. This means that the more a product is used, the more attractive it becomes. Over time as each part is used repeatedly on a specific metabolic pathway, especially when in successive experiments, its cost goes down. With the limited data that is available, it is predicted that total project costs could be cut down by 25% after its first successive use. It is also likely that these costs would be cut down several more times until it flattens as with each subsequent experiment more knowledge on that part is gained and intuitively, less errors are made.
+
-
</p>
+
-
<br><p>
+
-
One such example is with Amyris’ artemisinin project that spanned over the length of five years, costing $20 million. It was reported that 95% of the time spent was on finding and fixing unintended interactions between parts.
+
-
</p>
+
-
<br><p>
+
-
Due to the fact that one part must be used in conjunction with other sets of parts gives incentive to companies to create whole libraries. This is very similar to how software companies develop several programs that are able to cover multiple applications. Not only that, but there is opportunity for these companies to make profit by patenting some of these parts and making others openly available due to the strong modularity of the open-parts approach.
+
-
</p>
+
-
<br><p>
+
-
It is expected that companies will have their own individual parts needs. This means that other companies cannot just sit around and wait for another to develop a part. This also gives a type of competitive advantage as companies that share parts will not be losing their, ‘technological edge’ to other competitors. Since different companies have idiosyncratic needs and hence expertise, it proposes that community-based libraries will outperform individual companies. The industry will probably have a large number of small, distinctive customers, meaning that patent licensing will be less attractive and the open-parts initiative more so<sup>5</sup>.  
+
-
</p>
+
-
<br><p>
+
-
Normally, the value of a patent depends on the inventor’s initial R&D investment, but with synthetic biology parts it would depend on that as well as how many researchers have subsequently used that part. According to the law, this allows patent owners to capture both sources of value, which can be unfair to society as they must deal with high prices without getting anything more in return. The open-parts initiative sets the price of parts equal to zero, so it is naturally able to solve that problem. There are two incentives that will draw companies to an open-parts initiative. The first would be the opportunity to share R&D investments among multiple firms and secondly the opportunity to produce parts faster due to shared insights<sup>6</sup>.

About twenty years ago when software became standardized, it opened the path for Microsoft to come in, take over the industry and monopolize it. Can something similar potentially happen in the synthetic biology industry? At the moment, synthetic biology is what is called a ‘tipping market’. It is unstable and prone to monopoly. Building on this, the tipping dynamic is indifferent to whether or not the dominant parts constellation is open or closed. If for instance a mature industry is able to grab a hold of these shared parts, it can work towards this open-parts initiative. Though on the other hand, companies, out of necessity will also pay for closed parts, both solutions are equally viable.
+
-
</p>
+
-
<br><p>
+
-
Some other issues include an agreement on standard nomenclature for the parts, therefore when actually designing a database, controversies might come up. As well when collaboration occurs there must be adequate legal infrastructure. This must include a license specifying the rights and duties of members. One of the main legal problems is that gene data is unlike software, it cannot be copyrighted.  
+
-
</p>
+
-
<br><p>
+
-
Many pessimists towards the idea say that it is now too late for synthetic biology to use an open-parts collaboration. Now with Amyris’ advancement in the field it seems that this industry might monopolize and follow the path that Microsoft had. The fact that commercial synthetic biology receives so much government support shows a bit of laissez faire attitude. In America’s Department of Energy $350 million biofuel initiative there was no open-parts requirement at all. It is said that at least when Bill Gates cornered the software market he did it with private money<sup>7</sup>.
+

<br>

Kids were keen and interested in these activities, especially learning about various different concepts that they had not yet been exposed to. “Who knew that DNA could come out of your own cheeks?” was the idea we wanted to pass along- that every living organism contains DNA. From bacteria to animals.

<br/><h3 style="color:#0077be">PATENTS and Synthetic Biology</h3>
 
-
<br/><p>
 
-
The ideological reasoning behind applying for a patent lies in the fundamental incentive that it would bring forth financial rewards and a sense of monopolistic supremacy in an advancing market. The imposition of patenting technology has been deemed useful in many industries, most notably in electronics. However, it has also brought forth a considerable level of controversial dialogue in determining how historical protocols can be implemented within new technological streams that sometimes question the concept of man-made invention. For example, Craig Venter’s desire in protecting his synthetic cell research methodology gives him a deserving ownership, but his broad patent places a downgrading threat towards the field of synthetic biology. Ironically speaking, patenting is a legal practice that promotes innovation, but imposes a sense of apprehension for those who wish to adapt towards a more open-sourced strategy. This analysis focuses on the implications of introducing patent law to the field of synthetic biology as well as the practicality of gaining rights to a product not developed entirely by man, but with elements  arising from nature. 
 
-
</p>
 
-
<br/><h4 style="color:#0077be">Monopolizing Synthetic Biology</h4>
 
-
<br/><p>
 
-
The accrued financial and proprietary benefit of monopolizing an idea within a competitive market is indeed an accelerated advantage when a patent is granted. However, many have the misconception that monopolistic proprietorship has a standardized value to any industry it is applied to. For years, Professor John Sulston from the University of Manchester, a believer in promoting an open-source environment in the field of synthetic biology has proposed the implications that would arise should Venter receive approval upon his protocol in developing synthetic organisms.  Sulston states,
 
-
</p>
 
-
<br/><p><i>
 
-
"I hope very much these patents won't be accepted because they would bring
 
-
<br/>genetic engineering under the control of the J Craig Venter Institute (JCVI). They would
 
-
<br/>have a monopoly on a whole range of techniques (BBC UK, 2010)."
 
-
</i></p>
 
-
<br><p>
+
</div>
-
The irony in this matter is that the technological industry used the concept of monopolistic competition to drive both innovation and the development of products that would eventually overpower the market leaders. The reason that this concept cannot presently be applied is that synthetic biology is strongly reliant on collaborative construction. Patenting biological parts or processes will not motivate a group of scientists to pursue their research, but cause them to weigh the opportunity costs between their groundbreaking research and the hefty payments they would make to patent holders.

In the case of Venter’s claim, organizations such as the ETC group believe that Venter’s group is eyeing on a profit making opportunity. Hope Shands of the ETC group states, “The fledgling synthetic biology industry keeps talking about how they’re going to fix climate change – but these sweeping patent claims reveal that the companies are much more focused on securing profits than on human needs” (ETC Group, 2007). The multi-purpose use of a biological methodology would not only give Venter ownership to a scientific methodology, but to a range of applications that could be possible in the chemical, medicinal or environmental industries. Venter reported to Business Week, “If we made an organism that produced fuel that could be the first billion- or trillion-dollar organism. We would definitely patent that whole process” (ETC Group,2007). Many would dispute that this financial and market acquisition would only de-motivate other synthetic biology scientists and facilities to halt their research. But from looking at it from Venter’s perspective, wouldn’t anyone want to reap the rewards on a project that took 15 years and 40 million dollars to reach its success?

<h2 style="color:#0077be">Introduction</h2><br>
-
</p>
+
Synthetic Biology has been perceived as a field of science that has introduced tools, concepts and technologies which are sometimes sociologically and ethically insupportable. The non-scientific community has developed a stigma against the application of various synthetic biology technologies. The problem does not lie within the technology, but by an institution’s poorly executed strategy in educating the prospective end user about the relative benefit of its product. At times, the rate of technological advancements in the bioengineering industry surpasses the end-user’s ability to understand the necessity of the technology.<br><br>
 +
The science behind these synthetic biology tools has been the current driver in instilling a sense of appeal and intrigue within the scientific community. However, it is critical that the institutions that develop these technologies educate the non-scientific community of the importance and benefit of these tools to help relieve these evolving stigmas.<br><br>
 +
This year, the University of Waterloo’s Human Practices team’s focus was to develop a marketing strategy for their 2010 design project, the Staphiscope. The Staphiscope is an enhancement to the existing conventional plating methods that are used to detect Methicillin Resistant Staphylococus Aureus.<br><br>
 +
<b>The scope of the analysis includes:</b><br><br>.
 +
<li>What is the selling point of the product? What differentiates the Staphiscope from what already exists and is accepted by the non-scientific community?</li>
 +
<li>Does the concept of competition exist within synthetic biology? If so, how does an institution market the Staphiscope to optimize their opportunities for growth?</li>
 +
<li>How can the marketing strategy approach be differentiated to ensure that both the scientific and non-scientific community are exposed to the relative benefits of the Staphiscope?</li>
 +
<li>How do we channels the knowledge and learnings acquired within the synthetic biology industry and channel it to other stakeholders that will prospectively be impacted by the technology?</li><br>
 +
The purpose of the analysis is to ensure that the scientific industry understands the importance of bridging the scientific theory of a product to its economic feasibility. Moreover, it encourages institutions who participate in developing synthetic biology technologies to align their perception of a revolutionary design to what will be socially acknowledged by a non-scientific community.<br><br>
 +
<h3>What is the Staphiscope?</h3><br>

Methicilin resistant Staphylococcus aureus (MRSA) are bacteria whose presence has been quite problematic in terms of human pathogenic infections. Since its discovery in the 1880s, Staphylococcus aureus has been the known cause for several kinds of minor skin, and major post-surgical infections. Prior to 1940, mortality rates in relation to this pathogenic organism reached 80% (Deurenberg and Stobberingh, 2008.) The first wave of resistant S. aureus came two years after the introduction of penicillin for medicinal practice in 1940. In less than twenty years, most of the S. aureus strains known to man were unaffected by the antibiotic. In the late 1950s, a penicillinase-resistant penicillin was brought forth to the medicinal market; this was methicilin (Deurenberg and Stobberingh, 2008.) The bacterium's subsequent resistance to methicilin came two years after its introduction in 1959. The mecA gene responsible for methicillin resistance is also to blame for the organisms’ desensitization to several classes of antibiotics (Deurenberg and Stobberingh, 2008). This has led to the creation of the term: MRSA, now commonly used worldwide.<br><br>
 +
While an MRSA infection is much like a S. aureus infection, the difference comes in the lack of sensitivity of the MRSA to several classes of antibiotics. This makes MRSA infections a serious threat in both health and economical aspects.<br><br>
 +
The infection could be easily transferred directly (through regular skin-to-skin contact), as well as indirectly (through contamination of surfaces). The ease with which infection could occur, as well as the high mortality rate involved with the infection, make MRSA a serious threat to the health of patients worldwide (Durai et al., 2010.)
 +
There are only a few methods, which currently exit for MRSA screening. These are plating, liquid-broth inoculation, and PCR (polymerase chain reaction) assays. While these will be discussed in further detail later on in the report, it is important to note that these methods could be costly and time consuming, and could sometimes present incorrect results (Durai et al., 2010.)<br><br>
 +
In 2010, the International Genetically Engineered team at the university of Waterloo had been working on a method which can be used in supplement to the already-existing ones for the detection of MRSA infections. It is a proof of concept for diagnosing the presence of Staphylococcus aureus in an infection site before it has had the chance to create an infection. This synthetic biology–based diagnostic method will take advantage of the quorum sensing mechanism of Staphylococcus aureus, and utilize Escherichia coli as the sensor and reporter.

<h3>Who are the “Competitors”?</h3><br>
 +
Treatment of an S. aureus infection is of extreme importance, as outcomes can range from simple pustules to death. Early detection and treatment of S. aureus carriers can reduce healthcare costs and greatly improve the health of the patient. There are only a few methods currently available to hospitals for the diagnosis of S. aureus infection. These methods are time consuming, expensive and, in some cases, not very reliable.
 +
The purpose of the Staphiscope is to provide the option of accelerating the method of detecting S. aureus, without compromising reliability. It will be a particularly useful tool in speeding up the conventional methods of serial plating.<br><br>
 +
The following section analyzes the current products on the market and compares them to the Staphiscope.<br><br>

<h4>BD GeneOhm StaphSR</h4><br>
 +
<div style="text-align:center;"><img src="https://static.igem.org/mediawiki/2011/b/b1/Sectionanalysis_uw2011.png"></img></div><br>
 +
Traditional culture methods for the detection of S. aureus are usually 2-3 days. The new BD GeneOhm™ StaphSR delivers a diagnosis in less than 2 hours, using rapid real-time PCR. Also, it can simultaneously detect and differentiate Methicillin-Resistant S. aureus and S. aureus from a positive result (blood culture). Currently under development are additional specimen claims – nasal and wound samples. Nasal claim will be able to determine colonization status and the wound claim will add to the rapid identification of positively infected patients. Obtaining positive results in a timely fashion aids clinicians in the prevention and control of infections.
 +
<br><br>
 +
<h3>Method</h3><br>
 +
Specimen is prepared by transferring an aliquot of positive blood culture into a buffer team and then vortexed at high speed.<br><br>
 +
Cell suspension is lysed (via vortex and centrifuge) and heated. Then the lysis is cooled.
 +
Molecular reagents are reconstituted and the sample undergoes PCR.
 +
Results are obtained in about 1 hour.

<h3>GenoType MRSA</h3>
 +
Genotype MRSA uses DNA Strip Technology to identify both S. aureus and S. epidermidis cultures. Therefore, coagulase-positive and coagulase-negative staphylococci are differentiated. Simultaenously, the product can also detect Methicillin-Resistant S. aureus and S. aureus , which is incredibly important for therapeutic purposes. The test is performed from an overnight culture and guarantees results in only 4 hours.<br><br>
 +
<h3>Method</h3> <br><br>
 +
Culture is isolated from a sample or a primary culture is used.<br>
 +
DNA is extracted via methods producing amplifiable DNA from bacteria (for example    QIAamp DNA Mini Kit from Qiagen).<br>
 +
Nucleic acids are selectively replicated in an amplification reaction. In the next step, the amplicons are chemically denatured, since detection on the DNA•STRIP® is done using single-stranded DNA.
 +
During the conjugate reaction, the specifically bound amplicon is marked with the enzyme alkaline phosphatase and is then made visible in a colorimetric detection reaction.
 +
In this way, a specific banding pattern develops on the DNA•STRIP®. Using a test-specific evaluation template, the test result can be read out quickly and clearly.

As previously noted, synthetic biology encapsulates the field of biotechnology, software and computing. The current patent laws that have been put in place have generally been applicable to all industries individually. However, the field of synthetic biology is an amalgamation of two fields that have faced years of controversial debate in terms of granting or approving patents. The concern lied in the fact that patents related to inventions in biotechnology or software could be broad or narrow, but extensive enough to “hold-up” the concept of innovation and invention (Rai and Boyle, 2007 ).
+

</p>

<br><p>

Synthetic biology is being renowned as a stream towards the development of artificial life, which for some raises social, ethical and legal concerns. Patent Act 101 states that any subject matter that is found in nature is not deemed as patentable. However, if the product found in nature is modified or transformed to something that is novel and non-obvious, it holds credibility in attaining a patent. Looking at the synthetic cell created by Venter’s team, it is difficult to denote the “man-made” material in his composition. His cell includes a computer generated “minimal genome sequence” that is encapsulated within a bacterial cell (found in nature) and still hosts cellular machinery required to allow the cell to adapt and function within its environment. The modification is within the genome, but even that raises some debate on whether it can be patentable.

The software industry has always tackled with patenting mathematical and computational algorithms, particularly in concern was their level of broadness. In perspective to the field of synthetic biology, an algorithm is analogous to the creation of novel and modified genetic sequences, which give rise to new metabolic pathways and cellular functionalities. Yet again, the derivation of their new genetic sequence comes from the naturally degenerate genetic code, bringing up the question of whether this is entirely man-made. What is seen here is a disconnect, in that it would be difficult to set  fundamental patenting protocols for the field of synthetic biology, given the legal complications faced in both the field of biology and computing. This is where many may agree that an open-source strategy such as the MIT Registry of Standard Biological Parts would bring forth more progression, versus the time and effort it would take to validate the patentability of a biological part or process.

<h3>Methodology for Rating Scale</h3><br>
-
Below are other indicators to help define the relative benefit of introducing patent law, as well as the long-term threats that may hinder the advancement of research in the field of synthetic biology.  
+
The Competitive Analysis Matrix uses a format that divides the product’s market profile into several categories, providing a framework that ensures all issues are considered.  Each category is scored in the course of the ratings process (using a numerical scoring system). Products are scored 1 through 27; those facing greater competitive threats would wind up with an overall low market profile score. Please note that ratings represent, in the end, an opinion. Please note, thorough assessment of each product’s market profile requires a broader framework, involving a comprehensive review of the product’s competitive position.<br><br>

Pitching the Staphiscope to a Research and Development Company
-
</p>
+
When pitching the Staphiscope to the R&D industry, it is of paramount importance to establish its competitive advantage over traditional methods for S. aureus detection. To have a competitive advantage, a product or company must excel in at least one of the three following categories while remaining equal to its competitors in the others (Szarka, 2010):<br><br>
 +
<li>Market access</li>
 +
<li>Infrastructure</li>
 +
<li>Technology</li><br>
 +
Market access refers to how easily the target demographic can get the product. Even a revolutionary technology can be hampered by a lack of market access. Infrastructure is related to whether or not a supply chain exists, as well as facilities for production and distribution. The third point, technology, is where the Staphiscope excels; its superior technology is what will separate it from competitors. Other selling points of the Staphiscope include its speed, efficiency, and room for expansion (could this technique be applied to other cases?). Conversely, there are also barriers that must be overcome when pitching to the R&D industry; namely, one must avoid falling prey to “not invented here” syndrome (Szarka, 2010). This term applies to the mindset some companies have of only trusting in-house innovation, and can be difficult to alter. Other barriers include the lacking of Staphiscope use on a commercial scale, and public perception regarding E. coli. While the latter issue can be combated via a public awareness campaign, the former is simply a fact of any innovative technology.<br>
 +
Companies such as Amyris Biotechnologies and Codon Devices have attempted to commercialize in the field of synthetic biology. Their experiences provide valuable lessons that can applied to the Staphiscope (Wilan, 2005). The most relevant of these is that patent protection should be a serious concern when developing a novel technology, especially in such a burgeoning and competitive field. Consolidating IP ownership and control early is equally important, as doing so will prevent a lack of unified vision from stalling the Staphiscope’s progress. Of course, there are a plethora of patent and IP issues surrounding the field of synthetic biology that must be dealt with before or during the commercialization process. Chief amongst these is the scope of protection that can be provided to new technologies (Chugh  Sakushyma, 2009). Additionally, looking for a pharmaceutical partner can help ease the transition into commercialization.<br>
 +
It is important to realize that commercialization is a multi-year effort. As such, it can be beneficial to develop a commercialization plan (Office of Technology Transfer). This plan gives a general outline of what information the R&D industry will be looking for when it comes time to make a pitch. Details about market size and growth rates, predicted sales figures for the first five years, licensing agreements and more can all prove invaluable when attempting to bring a product to market.  Preparedness in regards to this information can make the difference between a successful pitch and an unsuccessful one.<br>
 +
In summary, pitching the Staphiscope to the R&D industry is a complex process that must be handled correctly to ensure its successful commercialization.<br><br>

<h3>How Do We Achieve Public Acceptance?</h3><br>
 +
For years, it has been believed that the prevalence of MRSA infections has resided within the walls of either a hospital or health care facility. Due to understated hygienic practices, a modified and relatively more virulent strain of Staphylococcus Aureus has also threatened several community based settings. In addition to Hospital Acquired MRSA, general health practitioners must also take into account the occurrence of community acquired MRSA.
 +
It is important to educate the public about the applications and relative benefit of the Staphiscope. Thus, there needs to be a channel of communication that allows for a transfer of knowledge between the scientific and non-scientific community. <br><br>
 +
<h3>Who Do We Want To Educate?</h3><br>
 +
Given that MRSA may not only be spread within a hospital but also within the community, there are quite a few demographics that would gain value in understanding the benefit of the Staphiscope.<br><br>
 +
<h3>Hospital Setting</h3><br>
 +
At least 2% of patients in hospitals or health-care facilities are likely to carry a strain of Staphylococcus Aureus that is resistant to antibiotics such as Methicillin. The following individuals are susceptible in contracting an MRSA infection: <br><br>
 +
<li>Individuals who have weak immune systems</li>
 +
<li>People receiving kidney dialysis or cancer treatments</li>
 +
<li>Individuals who have been hospitalized or have had surgery over the past year</li><br>
 +
<h3>MRSA within the Community</h3> <br><br>
 +
Patients who are discharged may have an inactive form of MRSA that remains colonized in their system. Thus, those who live within the community are still at risk of acquiring and suffering from antibiotic resistant Staph infections that are relatively more virulent. MRSA has been detected and acquired by healthy people in both institutionalized and individual based settings. The following individuals are susceptible in contracting MRSA in the community:<br><br>
 +
<li>Day-care facilities or facilities in which equipment of personal items are shared</li>
 +
<li>Military bases</li>
 +
<li>Individuals who get tattoos</li><br><br>
 +
<h3>The Strategy</h3><br>
 +
In the field of synthetic biology, there is an unrecognized paradox that hinders the level of interdisciplinary communication between the scientific and non-scientific community. The stigmas built outside the realms of a scientific community grow at a greater rate than a scientist’s ability to answer the plethora of questions surrounding the regulation, safety and potentiality of these synthetic biology technologies.
 +
Another problem lies in a scientific institution’s inclination to address the ethical concerns surrounding their synthetic biology technology or process. Generally an individual who has not be previously exposed to the field, will construct an ethical judgement proceeding the phase where a company is about to commercialize their product. At this critical stage of a company’s product plan, stakeholders are reluctant in addressing these ethical concerns as it may discourage their ability to advance and innovate their existing technology.
 +
Regardless of the threats that these ethical judgments have previously imposed, there is a necessity in developing an approach in which the end result is an internationally renowned sense of public acceptance and support.
 +
“Without public support and understanding of research into synthetic biology, both funding and regulation are unlikely to support significant scientific advances” (Gaisser, et. al, 2009).
 +
To address this issue, an expert committee in Europe supported by the New and Emerging Science and Technology programme set out a roadmap that outlines the four interconnected attributes that will instil a sense of public acceptance within the non-scientific community. These four attributes are:<br><br>
 +
<li>Scientific Milestones</li>
 +
<li>Knowledge Transfer</li>
 +
<li>Funding</li>
 +
<li>Regulation</li><br><br>
 +
This roadmap outlines that without the implementation of a knowledge transfer strategy, there is limited confidence attaining in achievements under the other three key areas of the model. Scientific milestones would not be achievable without a sustained level of funding provided through other groups impacted by the prospective commercialization of these synthetic biology tools. Moreover, regulation of synthetic biology tools is influenced by the ethically themed perceptions created by both the scientific and non-scientific community.<br>
 +
The knowledge transfer strategy would be an interdisciplinary model that would impact the following stakeholders:<br><br>
 +
<li>Natural and Social Scientists</li>
 +
<li>Engineers</li>
 +
<li>Industry Representatives</li>
 +
<li>Non-governmental organizations</li>
 +
<li>Non-scientific community (ie. hospital staff, hospital patients and members within institutionalized settings)</li>
 +
<li>Decision makers (ie. potential investors)</li>
 +
<li>Funding Agencies</li> <br><br>
 +
<h3>Knowledge Transfer Strategy</h3><br><br>
 +
In this context, knowledge transfer is the exchange of research knowledge between the institution producing the synthetic biology technology and their target end-user. The purpose of the knowledge transfer strategy is to develop a communication platform between all stakeholders to mitigate the unsourced perceptions, bias’ and stigmas against the field of synthetic biology. Moreover, it is better to develop an interdisciplinary team at the early stages of the technology development phases versus segregating the two communities until the technology is prospectively in its commercialization phase. <br><br>
 +
<h3>Method</h3><br>
 +
The following are examples of methods that can be used by the synthetic biology industry in promoting tools such as the Staphiscope to its potential end-users (ie. individuals within hospitals and community facilities)<br><br>
 +
<li>Development of an interdisciplinary network that consists of synthetic biologists, engineers, potential investors, and the general public</li>
 +
<li>Sustainable dialogue between all stakeholders within the interdisciplinary network. This can be achieved through:
 +
Workshops that aim in exchanging information to individuals that will benefit from the application of the Staphiscope in either a hospital or community based setting</li>
 +
<li>Educational materials that are specifically tailored to the different parties that could be impacted by the commercialization of the StaphiScope (ie. Hospital Microbiologists, Patients, and the General Public)</li>
 +
<li>Incorporating the General Public and other stakeholders at the research phase of the technology development process. This results in a mutual benefit to both the institution as well as the end-user in that they are able to collaboratively discuss the ethical feasibility of the technology.</li>
 +
<li>Use of knowledge broker- A knowledge broker is essentially an intermediary resource that assists in translating research knowledge to information that is comprehensible to a member that is not from the field of synthetic biology. An individual that has attained perceptions, knowledge and experiences from the scientific, business and social field is best suited to convey the importance of the Staphiscope to the stakeholders that have been listed above.</li><li>Partnerships between Synthetic Biology institutions and hospitals or other community based facilities.</li> <br><br>
-
<br><p>
+
Synthetic biologists must consider the importance of implementing an approach to help relieve the prospective stigmas that could potentially impact the relative success of their technology. The general public plays an influential role in the innovation capabilities of these synthetic biology technologies. Thus it is critical that these synthetic biology institutions involve the public and create awareness of their technologies at all stages of the research and development stage. Integrating a strategy that incorporates the exchange of knowledge is a fundamental leverage that would help create an aura of public acceptance and support all dimensions of the synthetic biology roadmap.<br><br>

<b>Weaknesses</b>
+
-
<br>
+
-
<br>1.The field of synthetic biology is different in the sense that innovation is not promoted through attaining proprietary rights to an entire process or genome, but through the collaborative use of fine, functional and specific biological parts
+
-
<br><br>2.Synthetic biology is multidisciplinary as it incorporates the field of biotechnology and computing, each has their own sets of legal rights, restrictions, and pitfalls
+
-
<br><br>3.In addition, lawyers would require a more extensive level of knowledge and proficiency in both fields
+
-
<br><br>4.Sometimes, hundreds of parts are necessary for the composition of one biological machine, and attaining rights to each part would create what is called to be a "patent thicket" (Rutz, 2009). Attaining rights to so many parts does not only hinder innovation, but is time-consuming and costly

<h3>Human Practices Commercialization Toolkit</h3><br>
-
<b>Opportunities</b>
+
-
<br><br>1.Patents add value, reputation and credibility to an invention. Although this legal concept is frowned upon in the R&D field, it brings a source of financial opportunity that would bring forth strategic partnerships and lump some funding to further progress research. At an economic perspective, patenting would be useful in advancing one's research.
+
-
<br><br>2.Patenting requires thorough documentation and characterization of each aspect of the part, streamlined patenting protocols could add standardization to the part development process
+
-
</p>
+
-
<br><p>
+
Following the Regional Jamboree, the Human Practices team began to develop the tools, templates and models that would assist a synthetic biology community and its associate stakeholders to understand the commercialization process. More importantly, our aim is to develop informational material that would achieve the integration of a knowledge transfer strategy in the field of synthetic biology. By streamlining the knowledge transfer strategy throughout each stage of the commercialization process, we are able to achieve a paralleled level of communication between the scientific and non-scientific community. Below is a sample of the toolkit our team has developed.<br><br>
-
<b>Threats</b>
+
-
<br><br>1.European patent law states that "iventions of commercial exploitation to morality are omitted from patentable rights" (Rutz, 2009).  The general public fears that if rights to a biological process or part are give they may be abused. Examples are biological warfare or the unintentional release of pathogenic organisms.  
+
-
<br><br>2."Patent sharks and trolls" (Rutz , 2009) may find it simple to file lawsuits against such patents. •On the other side of the coin, some have claimed that finding a patent application for a biological part is similar to finding a needle in a haystack. Moreover, it is not the job of a scientist to be rummaging around in identifying his legal rights to using a biological part, nor should his time be consumed by understanding the patenting process relevant to his field.

<h4>The Commercialization Road Map</h4><br>
-
<br><p>
+
-
The concept of patenting makes scientists cringe at the thought that their research and advancements would be diminished by the monopolistic power held by the broad patent holders within synthetic biology. There is currently no established set of specific protocols for patenting products in synthetic biology. Moreover, the attempt to blend the patent laws applicable to a range of disciplines to one as intricate as synthetic biology is difficult. Additionally, companies who wish to have a formalized process in examining and submitting processes would have to understand that a large number of additional resources would be needed to accommodate for the labour intensive, time consuming and costly process of patenting such biological parts. So the underlying question is that what is of greater value in today’s market, leading innovation through open-source strategies or banking on profit-making opportunities by securing an idea with a patent?

Before we attempt to understand the impact of synthetic biology on the business world as a whole, we must first understand what kind of an impact it will have on specific sectors. The goal of the industry analysis was to pick specific industries that we felt would be heavily impacted by the emergence of synthetic biology and attempted to understand their current situation as well as opportunities and threats facing each industry.

The oil industry has become an integral part of the society we live in for, transportation, food, healthcare, and communication. However, there is a dire need for alternative sources of energy and the world is beginning to turn towards biofuels for support in this area. Although there is immense promise in this area there is also many challenges to overcome such as reliance on environmental factors and adequate feedstocks. Although emergence of biofuels created through synthetic biology does not have the market potential to shift the whole method of biofuel production, politicians are optimistic that it has the potential to make an impact and have therefore taken measures to support the infrastructure of its’ development. The emergence of a viable synthetic biology biofuel would serve to excel the development of synthetic biology, particularly on the business stage.

This document outlines the strategies that are currently being used or proposed at the University of Waterloo but can be easily used on a wider scale by the entire iGEM community.

Our knowledge of diseases and treatments has advanced to an exciting point as has society’s perception of health problems and issues. However, as fast as our knowledge advances, diseases like H1N1 and HIV provide a pressure for the pharmaceutical industry to advance further and faster. In addition, aging populations and growing urban centres poise pharmaceutical companies for significant and meaningful innovation over the coming decades. The pharmaceutical industry is expected to grow to an $800 billion industry by 2011, expanding as a global force. Thus, synthetic biology, although faced with challenges in terms of legal and social concerns, is poised to have a significant impact on the pharmaceutical industry. Not only is there promise for curative treatments that would change how we view illnesses like HIV, there promises to be significant implications in the social, technological, and political realms. Unanswered questions about the handling of intellectual property issues will challenge the development of synthetic biology in the pharmaceutical industry as will ethical, safety, and political issues.

Unlike other industries, bio-remediation is an industry that has incorporated the use of genetic engineering and synthetic biology since the 1970’s. Based on the research conducted, there is a definitive understanding that this field poses an optimistic approach in achieving results that are environmentally friendly and cost-effective. The major setback with the field of bio-remediation is the intricacy of the techniques that are involved. Aside from the general publics qualms about bio-remediation procedures, even the scientific community does not have a holistic understanding of how the processes within bio-remediation work, or how to optimize a microbe’s “oil-eating” activity based on its metabolic characteristics. Most say that bio-remediation is a cost effective technique in treating vast oil spills, but it seems that investors and economists have not incorporated the cost of time and labour required in mastering the techniques involved. Once these techniques have established, there is a definite opportunity for this field to overpower the current invasive chemical processes that are being used as a last desperate resort in treating these environmental disasters.

<h4>Conclusion</h4><br>
-
<br><p>
+
The purpose of this analysis was to understand the relative feasibility of a synthetic biology tool from the perceptions of a scientific and non-scientific community. When devising a marketing strategy, most companies define a technology’s commercial success by its appeal towards investors or its ability to enter a market heavily saturated by other established technologies. Given that most synthetic biology institutions are still at their preliminary phases in terms of commercialization, it is critical that their product is widely accepted and acknowledged by all disciplines that are impacted or will be potentially exposed to the technology.<br>  
-
After conducting this research into the current and future position of synthetic biology particularly in the context of the business world, we are optimistic about the course that it will take. There are significant hurdles to overcome but overall there is a sense that synthetic biology will impart a positive impact not only in terms of specific products but also in terms of micro and macroeconomic impact.  
+
In the future we hope to take our research and methodologies and present them to the stakeholders discussed within the analysis. Our next steps are to identify institutions and facilities that would benefit from the use of the knowledge transfer strategy and develop sample activities or educational materials that can be used by these facilities to promote the Staphiscope. <br><br>

-
In this inquiry we have attempted to understand some of the important issues facing synthetic biology from a business perspective. In the future we hope to take our work a step further; we hope to take our knowledge, thoughts, and questions into the business world. Through interaction with business owners, scientists, legal specialists, and other stakeholders we hope to disseminate our findings and build on them. In the future we will continue to focus on our goal of deciphering the path that synthetic biology will take as it emerges in the business world.

 +
<li>Miniprepped all the intermediate steps, controls and final construction for submission to partsregistry.</li><br/>
-
Looked at pJET for PstI. Yes there is one, at position 5. This means that in Mph1103I+PstI digestion we expect fragments of of 153bp (the one we want) and 371bp (the one we don't care about).<br />
+
<h5>September 6th, 2011</h5>
-
Spread 70 µL of red LPS10 on X-alpha-gal+rif+kan.<br />

LPS: Two plates of pFB9010 have been recovered. In order to solve ambiguity, liquid cultures of Km and Sm were inoculated from plate 1 (most used). Also, plates of Km, Sm, Km/Sm were streaked with each of the 5 patches from each of plates 1 and 2 (where plate 2 is Sm only for some reason…although it should be both). This should solve which of the resistances is not functional. Results tomorrow.<br /><br />

<h4>Tuesday, August 17</h4><br />

+
-
Assembly: Nonodropping of both J23107 and I13507 stocks was performed. Digestion of J23107 with PstI and SpeI was unsuccessful. The 0.8% Agarose gel showed that the plasmid was not cut, since the uncut control beside it yielded the same bands.<br />
+
-
Assembly: Digestion of I13507 with PstI and XbaI was successful, although the bands were slightly off as related to the ladder. Suggestion was made that Gene Ladder Plus should be ran as 2uL of solution + 8ul of water. Also, it has ran fast before, so beware. Bands expected are 883 and 2057 (from I13507 in pSB1A2 plasmid). 883 was taken (appeared at around 1000, however), since it is an insert. The bands were gel purified and stored at -20 C.<br /><br />
+
-
<h4>August 18</h4><br />
+
-
 
+
-
digested and gel extracted I13453/E+X and I13458/E+S<br />
+
-
made 30 plates for ESQ activity<br />
+
-
performed half of competent cell procedure, let incubate on ice in 4°C O/N<br />
+
-
Results from yesterday were as follow:<br />
+
-
Growth from both pFB9010 plates on Km and Sm, but not on Km/Sm.<br />
+
-
Liquid cultures showed growth in Km, but not in Sm.<br />
+
-
Not sure what this means at the moment, so further tests need to be done.<br />
+
-
Transform remainders of pFB9010 stored at -20 C (nanodrop, transform)<br />
+
-
Try digestion of J23107 again – did not work AGAIN! Will attempt another time but with another lab’s REs, SAP and buffer.<br />
+
-
If digestion works, ligate with I13507. – did not work =(<br /><br />
+
-
<h4>August 19</h4><br />
+
-
 
+
-
Digestion of J23107 was re-done using REs, Buffer and SAP from another lab (except for SpeI, since it was not available from anyone else.) This did not work either.<br />
+
-
We think that maybe there is something wrong with the J23107 miniprepped stock in the -20C fridge, so we will make a new one. Took J23107 from frozen stock and streaked onto an Amp100 plate, as well as inoculated into Amp100 liquid culture. This will be miniprepped tomorrow.<br />
+
-
Set ligation of I13458+I13453<br /><br />
+
-
<h4>August 20</h4><br />
+
-
 
+
-
Miniprepped J23107<br />
+
-
Nanodropped and digested – SUCCESSFUL!!!!<br />
+
-
Gel Purified and Nanodropped<br />
+
-
Concentration according to nanodropping is ~ 1ng/ul = way too low.<br />
+
-
More J23107 and I13507 will be inoculated over the weekend, and will be minirepped and digested on Monday.<br />
+
-
Regarding LPS, took a Km20 plate which yielded good results, and inoculated it into the following liquid cultures.<br />
+
-
Km20, Km10, Km20/Sm100, Km20/Sm50,Km10/Sm100,Km10/Sm50, Sm50, Sm100.<br />
+
-
This was done to ensure that the concentration of Sm or Km is not too high in the liquid cultures (mass transfer accounts for erroneously high concentration in comparison to solid agar on plates.)<br /><br />
+
-
<h4>August 22</h4><br />
+
-
 
+
-
Results from inoculations of various Km/Sm concentrations were as follows:<br />
+
-
Contents Results<br />
+
-
Km10 +++ (red precipitate on the bottom)<br />
+
-
Km20 +++ (red precipitate on the bottom)<br />
+
-
Sm50 +++(very little white-ish red precipitate on the bottom)<br />
+
-
Sm100 -/+ (looks little bit cloudier than regular LB, but that could be due to re-suspension of the patches, since it was taken from a patch, not from a single colony)<br />
+
-
Km10/Sm50 +++ (red precipitate on the bottom)<br />
+
-
Km10/Sm100 +++ (no red precipitate on the bottom)<br />
+
-
Km20/Sm50 -/+ (looks little bit cloudier than regular LB, but that could be due to re-suspension of the patches, since it was taken from a patch, not from a single colony)<br />
+
-
Km20/Sm100 -/+ (looks little bit cloudier than regular LB, but that could be due to re-suspension of the patches, since it was taken from a patch, not from a single colony)<br />
+
-
 
+
-
This probably means that while the resistances are present in the genome, they are not expressed very strongly. Will attempt to grow colonies on plates with reduced Sm/Km. After, will attempt triparental mating again.<br />
+
-
innoculated J23107 into 5 liquid Amp 100 cultures, ready to be miniprepped tomorrow (Monday)
+
-
prepared Km10/Sm50, Km10/Sm100, Km20/Sm50, Km20/Sm100 plates and streaked pFB9010 on them. Results to be seen tomorrow. This was done, since liquid versus solid media has been giving varying results with this project.<br /><br />
+
-
<h4>August 23</h4><br />
+
-
 
+
-
There is no growth on any of the pFB9010 plates (with varying conentrations of Km and Sm)<br />
+
-
Miniprepped and nanodropped J23107 (concentrations are written on the tubes)<br />

<h4>August 26</h4>
+
-
 
+
-
Concentrated samples of digested J23107 (digestion was done with SAP) and I13507.<br />
+
-
Performed ligation (added ATP)<br /><br />
+
-
<h4>August 27</h4><br />
+
-
 
+
-
Ligation was ran on gel (big mistake....should have just went along with transformation right away, since results could not be seen on the gel)<br /><br />
+
-
<h4>August 30</h4><br />
+
-
 
+
-
Performed digest of J23107 again, except used FD Buffer instead of Green FD Buffer<br />
+
-
Ran on gel<br />
+
-
Sample appears as a smudge (potential contamination)<br />
+
-
Performed digestion of I13507 again, using FD buffer instead of FD buffer green.<br />
+
-
Ran on gel<br />
+
-
Could not see digest.<br />
+
-
Transformed ligation of “58+53” (quantification work)<br /><br />
+
-
<h4>Tuesday, August 31 - Friday, September 3</h4><br />
+
-
 
+
-
Performed digest of J23107 and I13507 AGAIN! This time, SAP was not added to the vector digest (usually, if it is a double digest, you don’t really need to add SAP. It helps in the case that one of the REs does not cut). WORKED!!!<br />
+
-
Transformed the ligation of J23107 and I13507<br />
+
-
Using 50µL of competent cells, 20µL of ligation reaction and 15µL of CaCl2(100mM solution)<br /><br />

Miniprepped I746104 and I13507<br /><br />
+
-
<h4>September 23</h4><br />
+
-
 
+
-
1. Nanodropped samples of I746104 and I13507. Results are as follow:<br /><br />
+
-
 
+
-
 
+
-
I13507 - [102 ng/ul] 260/280 = 1.87 <br />
+
-
I746104 (1) - [168.8 ng/ul] 260/280 = 1.81 <br />
+
-
I746104 (2) - [158.8 ng/ul] 260/280 = 1.82<br /><br />
+
-
 
+
-
 
+
-
Calculations for digestions: need 617.9 ng of insert, 300ng of vector.<br /><br />
+
-
 
+
-
 
+
-
1. Digests:<br /><br />
+
-

-
I746104 with SpeI and PstI 3ul I746104 1ul Pst 1ul Spe 2ul FD Green Buffer 12ul Nucl. Free Water 1ul SAP<br />
+
-
 
+
-
 
+
-
This was done in duplicate. Control: 1.5 ul I746104 without REs; 10uL reaction.<br />
+
-
 
+
-
 
+
-
I13507 with XbaI and PstI 7ul I13057 1uL PstI 1uL XbaI 2uL FD Buffer Green 9uL Nucl. free water<br />
+
-
 
+
-
control: 3ul of DNA, no REs, 10ul reaction.<br />
+
-
 
+
-
3. Left to incubate for an hour @ 37C<br />
+
-
 
+
-
4. Gel purified using protocol for purification from enzymatic reactions (used 60uL of Elution buffer for non-controls, 30ul for controls)<br />
+
-
 
+
-
5. Speed vac for 10 minutes on high.<br /> 6. Nanodropped<br />
+
-
 
+
-
 
+
-
I746104 (1) - 9.7 ng/uL <br />
+
-
I746104 (2) - 8.7 ng/uL <br />
+
-
I746104 (3) - 5.5 ng/uL<br />
+
-
 
+
-
 
+
-
I13507 (1) - 14.1 ng/uL<br /> I13507 (2) - 21.3 ng/uL<br /> I13507 (contaol) - 14.0 ng/uL<br /><br />

-
 
+
-
Vector 8uL<br />

-
Insert 6.5 uL<br />
+
-
10X lig buff 2.5uL<br />

-
ATP 1uL<br />
+
-
Nucl. free water 6<br />
+
-
total: 25.5 uL<br /><br />
+
-
 
+
-
The two I13507 were mixed, and 6.5 uL were taken from each into the 3 aliquots of I746104. Why is there 3 aliquots, when there was only 2 to begin with, you ask? Because Cveta lose the label on one of them, and couldn't tell which were the actual digests and which was the control.<br />
+
-
 
+
-
To fix this grave mistake:Cveta saved 2uL from each of the three tubes so we can run a gel tomorrow and find out which is which. If you are doing anything with the tubes, please ensure the labelling does not change.
+
-
Left to ligate at 16C in PCR machine.<br /><br />
+
-
<h4>September 24</h4><br />
+
-
 
+
-
Ligation of K359003 and I13507 was completed, plated on Amp100 and incubated overnight at 37˚C<br /><br />
+
-
<h4>September 25</h4><br />
+
-
 
+
-
Informed the lab volunteers of work done over the summer<br />
+
-
Shared the following with them:<br />
+
-

+
-
 
+
-
 
+
-
In Brochure form (please print with Acrobat Reader in the "short" duplex format, or otherwise I am not responsible for wasted paper)<br />
+
-
 
+
-
<h4>September 26</h4><br />
+
-
 
+
-
checked the I746104 digestions that went into ligation by gel, #1 is apparently a control.<br />
+
-
Transformed and plated the ligation (putative 003).<br /><br />
+
-
<h4>September 27</h4><br />
+
-
 
+
-
Incubated Amp100 K359003 plates grew well. Some bright pink colonies were visible, others were white.<br />
+
-
Two aliquots of ligation #2 and #3 were prepared<br />
+
-
3 pink colonies from each plate were inoculated from each plate into separate liquid broths of Amp50.<br /><br />
+
-
<h4>September 28</h4><br />
+
-
 
+
-
Miniprepped the 6 separate tubes, nanodropped, written concentration on side of the tube and stuck in second green box (the one labeled "2010 Parts Kit 2", disregard the meaning of that name), so it is easier to find.<br /><br />
+
-
<h4>September 29</h4><br />
+
-
 
+
-
6 clones were digested using the following gel layout:<br />
+
-
1: Ladder (2uL + 8uL MQ) <br />

-
1. Digests<br />
+
-
Sad news of the day: SpeI is not heat inactivatable (sp?). Some NEB heat inactivatable SpeI was found, so we shall try that one later.<br />
+
-
 
+
-
a. Digests # 1 to make K359008 003 cut with XbaI and EcoRI 006 cut with SpeI and EcoRI<br />
+
-
 
+
-
b. Digest # 2 to make K359009 003 cut with XbaI and EcoRI 007 cut with SpeI and EcoRI<br /><br />
+
-
 
+
-
2. Ligations The above digests were set for ligation. Two aliquots were made for each (but there was barely anything for the second one.) A -ve and +ve control were also included, where -ve = no DNA, +ve = Amp resistant plasmid lying around. Left tubes in PCR machine overnight at 16C.<br /><br />
+
-
 
+
-
 
+
-
<h4>October 3</h4><br />

-
 
+
-
Team photos taken<br />
+
-
Looked through our fridge and freezer. Put all relevant microfuge tubes into the "2010 Parts Kit 2" green box.<br />
+
-
Could not find 006, nor 007 but did find 008 and 009 and so,inoculated 3 tubes for each.<br />
+
-
Digested parts 003, 006, 007, 008, 009 and pSB1C3 with E + P. Purified these digests and then left them over night in part + pSB1C3 ligations. Also, made 3 inoculations of pSB1C3 and 2 inoculations each of 009/008 (total of 7). These are all on the shaker.<br /><br />
+
-
<h4>Tuesday, October 19</h4><br />
+
-
 
+
-
Miniprepped pSB1C3/008/009 (9 tubes in total) from the incubator.This is required in the case that the transformations are unsuccessful,so that we can start over.<br />

Our project is not expected to raise any safety issues in terms of researcher, public or environmental safety. The health risks associated with the organisms used and the work completed could be classified as very low to moderate. None of the biobricks we submitted raise any safety concerns. In terms of biosafety rules to be followed, we would consider Biosafety Level 2 to be a sufficient indicator of safety requirements. This stems from the fact that the organisms involved are Escherichia coli and Staphilococcus aureus. However, in practical use (e.g., hospital setting), level 3 facilities would be required. This is to account for several factors, including the increased potential for highly pathogenic strains in the vicinity, as well as the very unlikely possibility of a pathogenic strain of Escherichia coli obtaining the AIP sensing characteristics of our StaphiScope model.  In terms of biosafety issues which could be useful for future iGEM competitions, the appearance of a desired biobrick into a pathogenic strain of bacteria would be the biggest concern. The potential for such an occurrence would be limited by Biosafety Level 2 rules, as described below.

The Ribozyme Project is not expected to raise any research, public or environmental safety concerns other than those normally associated with Biosafety Level 2 organisms, such as Escherichia coli (DH5-alpha), which is classified as very low to moderate. The use of this project is primarily reserved for research and laboratory use, therefore, should not purposefully be exposed to the public or environment except after further testing in its specific applications (such as with particular fusion proteins). Furthermore, the basis of our project is to establish a self-excising sequence (ribozymes), which should limit the expression of any intervening sequences to the RNA level. If the intervening sequence were something of environmental or public relevance (such as antibiotic resistance), the experimental design indicates that the sequence will be removed and, thus, not expressed. This is a relevant contribution of the design in limiting expression to the RNA level, which eases environmental hazard concern upon the accidental release of a GMO containing this biobrick. Therefore, the new biobrick parts submitted should not raise any safety issues.

In Vivo Protein Fusion Assembly Using Self Excising Ribozyme

ABSTRACT

Introns, self-excising ribozymes, can become a useful tool to create in vivo protein fusions of BioBrick parts. To make this possible, intron sequences are used to flank non-protein parts embedded in coding sequences. An intron sequence with an embedded recombination site is capable of in vivo insertion of a compatible protein fusion part. As an example, a GFP-fusion was created with an intervening lox site that is removed from the final protein using the intron to form a fully functional GFP protein. In vivo protein fusions can be applied to a larger number of modular systems to make complicated expression systems, such as synthetic antibodies or plants capable of Cry-toxin domain shuffling.

Project


The goal of Waterloo's 2011 iGEM project is to implement self-excising ribozymes (introns) as biobricks. But first, what are self-excising ribozymes? Ribozymes are ribonucleic acid (RNA) enzymes and enzymes are reaction catalysts. So ribozymes are just RNA sequences that catalyze a (trans-esterification) reaction to remove itself from the rest of the RNA sequence. Essentially these are considered introns, which are intragenic regions spliced from mRNA to produce mature RNA with a continuous exon (coding region) sequence. Self-excising introns/ribozymes consist of type I and II introns. They are considered self-splicing because they do not require proteins to intitialize the reaction. Therefore, by understanding the sequences and structure of these self-excising introns and making them useable, we can use them as tools to make other experiments easier.

1.0 INTRODUCTION

This design provides a reasonable basis to implement in vivo applications involving RNA level regulatory sequences. The fusion proteins produced surpass strictly what is coded in the DNA. As a result of incorporating ribozyme segments in between two halves of the protein coded in the DNA construct, a regulatory sequence (such as a recombination site) could be included. Since recombination sites can interrupt the functional production of a protein if translated fully (resulting in excess amino acids in the polypeptide), the incorporated ribozyme portions remove them before the translation phase of gene expression so that a functional protein is produced. For example, Cry proteins, which account for the insecticidal activity (toxicity) of Bacillus thuringiensis, could be the fusion protein produced for a particular insecticide. Using our experimental design, the sequence containing the code for the Cry protein (at the DNA stage) is split by ribozyme segments containing a recombination site. In this case, the recombination site is the regulatory sequence that will be removed once transcribed into RNA. At the DNA level, recombination (shuffling) will occur, exchanging DNA strand segments. Therefore, when the shuffled DNA sequence is transcribed into RNA, the recombination site is spliced out of the sequence with the ribozymes, and the resulting RNA code is different than that of the un-shuffled code. Consequently, the translated Cry protein is different. This system would oppose pesticide resistance among the target organism.


1.1 A Little Bit About Group 1 Introns

All group I introns in bacteria have presently been shown to self-splice (with few exceptions) and maintain a conserved secondary structure comprised of a paired element which uses a guanosine (GMP, GDP or GTP) cofactor. Conversely, only a small portion of group II introns have been verified as ribozymes (they are not related to group I introns) and generally have too many regulators to easily work with. It is mainly the structural similarity of these introns that designates them to group II. We will mainly be working with group I introns, such as the Staphylococcus phage twort.ORF143.



Group I introns contain a conserved core region consisting of two helical domains (P4–P6 and P3–P7). Recent studies have demonstrated that the elements required for catalysis are mostly in the P3 to P7 domain. They are ribozymes that consecutively catalyze two trans-esterification reactions that remove themselves from the precursor RNA and ligate the flanking exons. They consist of a universally conserved core region and subgroup-specific peripheral regions, which are not essential for catalysis but are known to cause a reduction in catalytic efficiency if removed. To compensate for this, a high concentration of magnesium ions, spermidine or other chemicals that stabilize RNA structures can be added. Thus, the peripheral regions likely stabilize the structure of the conserved core region, which is essential for catalysis.


1.2 Trans-Esterification Reactions

The secondary structures, such as P6, formed by group I introns facilitates base pairing between the 5' end of the intron and the 3' end of the exon, as well as generates an internal guide sequence. Additionally, there is a pocket produced to encourage binding of the Guanosine cofactor. The Guanine nucleotide is placed on the first nucleotide of the intron. The 3'OH of Guanosine group nucleophilically attacks and cleaves the bond between the last nucleotide of the first exon and the first nucleotide of the 5' end of the intron; concurrently, trans-esterification occurs between the 3'OH and the 5'phosphorous from the 5' end of the intron. Subsequent conformational rearrangements ensure that the 3'OH of the first exon is placed in proximity of the 3' splice site. In this way, further trans-esterification reactions and splicing occurs.


Retreived June 21, 2011 from Self-Splicing RNAs [1] This diagram shows the trans-esterification reaction and splicing of group I introns from a sequence.

1.3 Fusion Proteins

Fusion proteins are combined forms of smaller protein subunits and are normally constructed at the DNA level by ligating portions of coding regions. A simple construction of traditional fusion protein involves inserting the target gene into a region of the cloned host gene. However, the subsequent project design, in its simple construction, interrupts the cloned protein with ribozyme sequences flanking a stop codon. The method proposed deals with excision and ligation at the RNA level, therefore, the unaltered DNA sequence does not code for a functional protein. The ligation of protein coding sequences can create functional fusion proteins for many applications including antibody or pesticide production; however, this method of production is limited to producing the same fusion protein each time since the sequence is not modified in between the transcription and translation phases of gene expression. One disadvantage of this is the resultant resistance of a pathogen to antibodies or a target organism to pesticides. For example, a specific pesticide (Cry toxin) may eventually not be effective to its target plant if subsequent plant generations inhibit its uptake, overproduce the sensitive antigen protein so that normal cellular function persists, reduce the ability of this protein to bind to the pesticide or metabolically inactivates the herbicide. Similar mechanisms contribute to antibiotic resistance. Any resistant organisms will inevitably prevail in subsequent generations. Recombination sites could potentially be incorporated into the subsequent project design to circumvent some of the difficulties with traditional fusion proteins as a result of host resistance. However, recombination sites may interrupt the functional fusion protein from forming. Ribozyme segments at the RNA regulation level can potentially remove disrupting sequence after such shuffling occurs. Therefore, the intervening sequence maintains its DNA level functionality but is removed when no longer needed at the RNA level. Fusion protein design focused on the DNA level does not have this dynamic regulation. 

1.4 The Cre-Lox System

In bacteriophage P1 exists the cre enzyme and recognition sites called lox P sites. This viral recombination system functions to excise a particular DNA sequence by flanking lox P sites and introduce the cre enzyme when the target is to be excised. The cre enzyme both cuts at the lox P site and ligates the remaining sequences together. The excised DNA is then degraded. This is similar to our project design; however, instead of requiring the addition of an enzyme at the desired excision time, the self-excising nature of ribozymes automatically functions during the normal process of gene expression (RNA level). 

2.0 PROJECT IN DETAILS


2.1 EXPERIMENTAL DESIGN


Our protocol will involves the insertion of a functional protein, split by the self-removing elements, between CUCUUAGU and AAUAAGAG in the P6 region of twort.ORF143. GFP (green fluorescent protein) is split into two parts, which will be referred to as GFP1 and GFP2. With a constitutive promoter, GFP1 and GFP2 will be separated by a class 1 A2 intron split into two (for now, IN1 and IN2) sequences that flank another sequence inserted into the P6 loop, which was chosen because anything attached to this region will remain outside the protein. Note that this experimental design also contains an in frame stop codon, which is expected to be spliced out of the sequence with IN1 and IN2 and will utilize the RFC53 convention. Following GFP2 is a transcriptional terminator (TT). The method of making this construct is detailed in RFC53. Below is Figure 1 through Figure 3. They illustrate the order of parts in the design and the trans-esterification reaction that results in a function GFP:



Figure 2 shows the experimental design of the sequence immediately following transcription. It contains a constituent promoter, RBS Ribosome Binding Site), GFP1, IN1, in-frame stop codon, IN2, GFP2 and TT. The dotted lines and scissors indicate that the introns will be spliced out of the sequence at these points, however, the introns are self-excising.



Figure 3 is a representative view of the sequence folding in order to catalyze the trans-esterification reaction, however, there are many hairpin loops actually formed. This is the process of post-transcriptional modification. Specifically, Group I intron splicing events utilize a guanosine nucleotide to bind another sequence and dislodge the 5' site, then the cleavage initializes another splicing event with the remaining hydroxyl end to dislodge the rest of the RNA sequence and ligate the remaining exons. The remaining fusion protein code is different than that of the primary transcript.



Figure 4 shows a non-disruptive ligation scar and active GFP after the self-excision of IN1 and IN2. This is the modified RNA transcript prior to translation..


2.2 CONSTRUCTION MAPs AND RFC 53

As per RFC 53 convention, enzyme digestions are followed in the particular order outlined below. The standard procedure makes this technique reproducible, therefore, more easily extrapolated to other applications. Compared to other protein fusion methods, this design facilitates additional regulation within necessary guidelines. However, the embedded post-transcriptional modification in this design is a complication to consider in simpler designs where regulation at this level is not necessary. As such, unnecessary bulk in plasmid vectors is known to add to metabolic load and decrease replication rate compared to non-plasmid carriers.
2.2.1 General Construction Map

Figure 5 graphically shows the laboratory procedure for the experimental design in the form of an enzyme map:



  • K576005 contains the first component of GFP (GFP1)
  • K576003 contains the first part of the intron sequence (IN1
  • J61046 contains the lox site
  • K576006 contains the second component of GFP (GFP2)
  • K576004 contains the second part of the intron sequence (IN2)
  • K576007 contains GFP1 and IN1
  • K576009 contains GFP1, IN1 and lox1
  • K576011 contains the promoter (P), ribosomal binding sit (RBS), GFP1, IN1, lox site, IN2, GFP2 and transcriptional terminator (TT). This is the final construct (experimental design)

  • 2.1.2 Controls' Construction Map

    Controls are necessary to prove that the design of this experimental investigation is functional and more practically for comparison of fluorescence in the laboratory. In the positive control, GFP1 and GFP2 flank either RFC25 or RFC53, which will not disrupt translation regardless of the linker. Therefore, fluorescence is expected. The experimental run will ideally show fluorescence resulting from the self-excision of IN1 and IN2.



    Figure 6 represents the positive control. For consistency, GFP1 and GFP2 are separated by RFC53 (RFC25 could have also be used), which should not disrupt expression of a functional GFP.


    In the negative control (using the same constitutive promoter), GFP1 and GFP2, followed by a transcriptional terminator, flank RFC10 (Request For Comments) resulting in a stop-codon-containing scar. No fluorescence is expected for this component (background) because translation is interrupted. This is meant to control for the possibility of a non functional fusion protein. The expectation is that this fusion of GFP1 and GFP2 will not fluoresce, which is a consequence of some fusion protein techniques. Figure 7 shown below details the negative control design:




    Figure 7 is an illustration of the negative control containing the interrupted GFP with an in-frame stop codon, ensuring that it is not expressed. Since this sequence contains no excision sites (Group I introns), we do not expect any modification to this area of the RNA.


    The figure below shows the construction map for the controls.


  • K576005 contains the first component of GFP (GFP1)
  • K576006 contains the second component of GFP (GFP2)
  • K576013 contains the promoter (P), ribosomal binding site (RBS), GFP and transcriptional terminator (TT). This is the positive control.
  • K576005 contains the first component of GFP (GFP1))
  • J61046 contains the lox site
  • K576006 contains the second component of GFP (GFP2)
  • contains the promoter (P), ribosomal binding site (RBS), GFP1, lox site, GFP2 and transcriptional terminator (TT). This is the negative control.

  • 2.3 MAKING THE CONSTRUCT WITH RFC 53



    Figure 9: Making the Construct: Parts were sequenced into PUC57, digested and ligated into PSB1C3.

    Figure 9 is a flow chart of the general work flow involved in the construction of our experimental plasmid, as per RFC53 conventions.

    1. 1) The insert is isolated through a series of enzyme digestions. One intron (in blue) is shown here as a representation. The insert is isolated for subsequent ligation.
    2. 2) Similarly, the pSB1C3 vector is isolated through enzyme digestion. Note that "N" indicates that this is the vector portion. The vector is also isolated for the ligation step. It must also be noted that pSB1C3 vector contains a cut site of SacI, an enzyme that is used in RFC 53. Relocating the part in BBa_K371053 resolves this issue.
    3. 3) The two components (insert and vector) are ligated together to produce the final construct.
    4. 4) According to the experimental design, the final construct will contain self-excising ribozymes, which in the last step result in a non-disruptive ligation scar and, therefore, the expression of GFP.


    2.3 Preliminary Testing


    Although completion of a preliminary version of the final construct was achieved, lack of GFP fluorescence proved suspicion of questionable band placements during second and third stage electrophoresis. Final diagnostic digestion reaction confirmed abnormalities from designed constructs. Testing via digestion was completed for every intermediate, control and final constructs. Consequently, BBa_K576003, K576004, K576005, and K576006 were the only parts able to be confirmed. All the other intermediates and constructs have questionable band location which disrupted final construct fluorescence.



    Figure 10: shows the diagnostic digestion from September 16, 2011: All subclones shown to be correct, however, positive control not correct. Relative placement of GFPs and INTS required further verification and showed incorrect placement. This accounts for lack of fluorescence in final stage.


    The above electrophoresis picture describes the resultant bands from the diagnostic digestion. Although bands 5, 6 and 7 (sub clones) have been confirmed, the adjacent positive control (band 8) and all GFP and intron digestions are not consistent with the expected patterns. The GFP-INT and GFP-INT-lox constructions (bands 9, 10 and 11) have been verified as inaccurate. The questionable placements of these bands indicate that the cut sites, thus the fragment length and containing sequence, do not match the planned construction. Therefore, it is not likely that they contain functional GFP, introns or lox, which would result in a lack of fluorescence in the final stage of construction. Further testing to reconstruct the contaminated clones is necessary for the functional final product; however, lab work has stopped due to time constraint. A diagnostic digestion at each step is recommended to circumvent any similar issues upon the continuation of this project.


    3.0 PRACTICAL APPLICATION


    The biggest advantage of the ribozyme project is the ability to create in vivo protein fusions. These can then be applied to a larger number of modular systems that can be used to make complicated expression systems. One such system is the creation synthetic antibodies. If protein sequences are flanked by intron sequences and then set up along the same stretch of DNA, different combinations of fusion proteins will be created based on how the intron excision occurs. Another system where the ribozyme project can be applied is DNA shuffling experiments. The Cry toxin is used as an effective biopesticide, however for now it has a very small range of insects that it effects. The ways to increase its range would be to change the structure of one of the vital domains so that it is able to recognize a wider spectrum of receptors in the host mid gut cell. To create different variations of this domains an in vivo DNA shuffling experiments using the ribozymes could be carried out.

    Motivation and Goals

    This year’s modelling project focused on extending the work done by the modelling team in 2010.


    Waterloo’s 2010 iGEM project, "Staphiscope", utilized amplifier parts developed by Cambridge in 2009 to detect low levels of Staph Aureus. These amplifier parts were characterized by the Cambridge team, but only under control of AraC/pBAD promoter, which differed from the promoter used in our 2010 Staphiscope project.


    In order to characterize the amplifiers, a parameter scan was undertaken to find promoter-independent Hill parameters of each amplifier, consistent with data of full system. However, empirical verification of our results was lacking. This year, we sought to obtain this data, which (in conjunction with Cambridge data and model), would allow us to find Hill parameters for each amplifier.


    Model

    To allow for comparison of data, we used the same model as Cambridge in 2009.


    In this model, araC represses the pBAD promoter in the absence of the inducer, arabinose. When arabinose is present, it binds to araC, preventing repression of the promoter and allowing transcription of reporter (GFP). This situation is modelled by a Hill function; we seek the Hill parameters of this function.


    Thus, when AraC/pBAD system is induced with arabinose, we expect to see a steady increase of fluorescence from a low level, followed by a plateau of fluorescence at steady state.


    Method

    To measure fluorescence, we closely followed the assay described in the paper "Measuring the activity of BioBrick promoters using an in vivo reference standard", in the section "Assay of Promoter Collections".


    Three cultures were grown overnight at 37 degrees Celsius with spinning at 200 rpm: untransformed BW27783, BW27783 containing BBa_I0500, and BW27783 containing BBa_I20260. These were then diluted 1:100 and regrown for roughly 4 hours under the same conditions. They were then diluted to an OD between 0.05 and 0.09, and regrown for 1 hour, again under the same conditions.


    After this, the cultures were diluted into a 96-well plate at 8 different concentrations of inducer (arabinose), ranging from 0 to 6.4 uM. The plate was then incubated in a Wallac Victor3 multi-well fluorimeter at 37 degrees Celsius, and repeating measurements of absorbance and fluorescence were taken at 10 minute intervals, with shaking after each measurement. Untransformed BW27783, at each concentration of arabinose, was used to measure background fluorescence, and wells containing only broth were included to measure background absorbance. The machine settings used were identical to those described in the paper referenced above.


    With this data, we aimed to calculate the steady-state per-cell GFP concentration during log-phase growth, for both BBa_I0500 and BBa_I20260 (measurement kit for the standard promoter, J23101). The ratio of these values would then characterize the strength of the AraC/pBAD promoter in units of RPU. The justification for this approach can be found in the supplemental material of the paper referenced above.


    Results

    The results of the experiment were anomalous, and considered too unreliable to be conclusive. There was no clear relationship between cell fluorescence and inducer concentration.


    The fluorescence curve did not qualitatively match the predictions of the model; across all concentrations, and for each of the 3 cultures, we observed a high initial fluorescence, with a rapid drop to a lower steady state value. For each culture, this drop in fluorescence aligned well with the growth curve.


    In addition, the untransformed BW27783 cells exhibited consistently higher fluorescence than cells containing BBa_I0500, which was highly anomalous. Because of this, we could not reliably use these cells to measure background fluorescence.


    Below, a sample graph of Total Fluorescence is shown for each of the 3 cultures. These are curves of the total fluorescence for each culture, averaged over 3 replicates for each culture.


    Discussion

    It is believed that an error in our strain of BW27783 is most likely responsible for the anomalous qualitative features of our data. This is because for each concentration of inducer, the untransformed BW27783 cells exhibit a fluorescence curve highly similar to that of BW27783 containing BBa_I0500, and yet the untransformed cells should not be expressing GFP.


    Prior to the measurement assay, BW27783 cells transformed with BBa_I0500 were plated and examined for fluorescence, both with and without the presence of inducer. The uninduced cells were not found to fluoresce, while the induced cells did fluoresce. The fluorescing cultures were used to make the frozen stock of BBa_I0500 which was used in the measurement assay. This indicates that our untransformed BW27783 should not fluoresce without the presence of inducer. Furthermore, the untransformed BW27783 cells used in the measurement assay were at no point prior to the assay exposed to arabinose.


    To explain the fluorescence of the untransformed BW27783 in the measurement assay, it is speculated that our strain of BW27783 exhibits a rapid production of GFP in response to even low concentrations of inducer. Experimental error is also a likely source of inaccuracy in the data, although the qualitative features described were consistent across 3 trials of the experiment. Research into these results is still ongoing.


    University of Waterloo: iGEM OUTREACH


    The purpose of UW iGEM Outreach has always been and will continue to be the connection between our community and us. To help build a better understanding of synthetic biology, how it has affected the world around us and to create a basic, fundamental knowledge of the subject that can be incorporated into the way we see things. That perspective can be positive or negative, but we aim to provide the baseline knowledge required that will allow our community members to form a fact-based opinion.

    This year, UW iGEM: Outreach focused on designing and running workshops targeted at schoolchildren. We hoped to share our love and passion for biology with tomorrow's future scientists and engineers. We plan to continue building on what we currently have and to eventually develop a complete syllabus for all grade levels. These workshops will be available for download for other educators and enthusiasts interested in their own outreach.

    Workshop Materials



    We have submitted two community bricks! One for our Grade 12 workshop and the other for our Engineering Science Quest activity for Grades 3-4. The downloadable material is the same as what you can find here on our wiki page.
    -Synthetic Biology and You: Interactive Workshop for Grades 11-12
    -All About Bacteria: How Clean Are Your Hands?

    Grades 3-4: All About Bacteria - Outline | Handout (Duration: 2-day workshop, 1.5 hours total)
    Grades 5-6: All About DNA - Outline (Duration: 1 hour)
    Grade 12: Synthetic Biology and You - Materials | Ppt (part 1) | Ppt (part 2) (Duration: 2-3 hours)

    Are you interested in doing any of these activities with kids around this age? Feel free to use any of our materials above and/or contact us at uwigem.outreach.hp@gmail.com. It is an inexpensive, interactive and fun way to have kids involved in genetics, microbiology and synthetic biology at a very early age. And definitely a lot of fun!

    Events


    We were also fortunate enough this year to have been given the opportunity to run our workshops at two different outreach events, both of which were on a grand scale. Now, we'd like to share our experiences with you.

    Grade 12 Outreach Workshop: March 25th, 2011


    The first was an organized Grade 12 workshop aimed at biology students to gain a better understanding of synthetic biology, the industries it has been affecting, career prospects as well as two hands-on activities. Over the planning span of 3 months, this event was organized in close accordance with the Kitchener-Waterloo school board and with the Marketing and Recruitment Co-ordinator for Science at the University of Waterloo. Through the creation of a brochure and meeting with individuals from the school board we had sent out an invitation all across the district for students to come in for our event. Eventually we had gotten more than 85 students to attend, which was great as it was the first time we had implemented this idea.

    The next step had then been to recruit interested volunteers for the event so we could have our own students give a helping hand and who shared the same passion of sharing knowledge as we did. In order to facilitate this we had sent out emails, gone to various lectures and talked to students all over campus to get them involved. After recruiting 12 volunteers the brainstorming process had begun. We had wanted to have an interactive workshop where students were not just listening to us talk, but were actually involved in a stimulating activity that they could be excited about. The first part of our presentation looked into what was synthetic biology, what were Genetically Modified Organisms (GMOs) and what were the positives and negatives of them. Once that was through we started the first event. The first event we had was to talk about our very own Canadian genetically enhanced Yorkshire pig called the EnviroPig™. It has the capability to digest plant phosphate more efficiently than traditional Yorkshire pigs, which do not contain the enzyme to break it down, phytase. This gene can be found in E.coli which had been inserted into a pig embryo to allow it to produce phytase in its salivary glands. This is a real technology in Canada and is currently a very hot topic of debate among many citizens, so we thought it would be ideal to introduce students to the world of biotechnology right in their very own backyards. Once students had been exposed to the information, we had given them a package which we had compiled giving the positives and negatives of societal, technological, ethical, environmental and economical issues.

    Of course, it did not end there! Students were then put into groups of 5 and as mentioned above, one of the key goals of UW iGEM Outreach is to allow members of our community to make informed decisions based on facts. Supplied with markers and paper students were to give a 1-2 minute presentation on why they did/did not believe that the EnviroPig™ should continue receiving funding from the government of Canada. The best and most convincing presentation won- we had great discussions from the negative aspects to positive aspects to even a compiled rap song about the EnviroPig™!



    After the first event we continued on with our presentation. Here we discussed current industries that had been affected by synthetic biology. This incorporated the pharmaceutical and biofuels industries specifically. We discussed how pharmaceuticals had incorporated an aspect known as biosynthesis where they could customize and fine-tune certain pathways using standardized parts in order to provide efficient and precise drug delivery systems. In biofuels we talked about first and second generation biofuels and how the use of synthetic biology has the ability to create a ‘superbug’ to look for corresponding metabolic pathways for yielding ideal results. After this we did the second activity.

    The second event that had been implemented was to incorporate what we do in our labs, outside of the lab. Essentially, we wanted to introduce the idea of synthetic biology to students and how it was an extension of what we knew as genetic engineering and consisted of students not just from science but from math, engineering and computer science. The activity called, ‘Design Your Own Pathway’ gave a series of scenarios we had given students with a library of BioBricks to create a certain pathway. Progressively each scenario was harder, more complicated and required the use of multiple BioBricks. The BioBricks that we had used were from the library and were real parts. Essentially this was to enable students to have a feel of how we have a ‘mix and match’ concept when it comes to synthetic biology. The activity had been set up as a relay race, where students in the same teams as the previous activity had to race each other to finish all scenarios. The activity and concept had been such a success that after the workshop teachers had asked to use our activity in their own classrooms.



    Finally, we completed the presentation with a discussion of career paths that students could pursue that did not necessarily involve working in a lab. We wanted students to understand that the world of synthetic biology and biotechnology encompasses the involvement of individuals from multiple backgrounds and can penetrate into many different industries.

    There was such an interest in our workshop that our prospects for the next one are aimed at more than 150 students. One thing’s for sure, mission accomplished and there’s definitely more to come! Would you also like to have your own workshop at your high school or university? Please feel free to view the downloadable materials for the presentation and two activities or contact us at uwigem.outreach.hp@gmail.com.



    Engineering Science Quest: July-August 2011

    Founded in 1990, the Engineering Science Quest or ESQ is a not-for-profit program that operates with the goal of exposing children in the Kitchener-Waterloo region to the world of engineering, science and technology through engaging them in a variety of hands-on activities. Promotion is primarily done through workshops in-school but also have satellite programs which reach out to rural and Native communities as well.

    This is not the first time that UW iGEM has been involved in ESQ and we are proud to say that our continued involvement has allowed us to develop a standard set of activities which we are pleased to present to kids ranging from Grades 3-6 with more than 100 students. Currently we are also developing ideas for older kids that are similar to our activities from the Outreach workshop we had in March for Grades 10-12 and for even younger kids from Grades 1-2. Through involvement with managers specifically for ESQ this year we were able to have continual workshops every week from July 11th- August 12th, 2011. This was done with the recruitment of volunteers who again shared the same passion as we did in connecting with our community to facilitate that baseline knowledge; to get students introduced or even extend their knowledge on the world of synthetic biology and biotechnology.

    The first activity for Grades 3-4 was called, “All About Bacteria: Do You Really Need to Wash Your Hands?” In this activity we introduce kids to the idea of biology, bacteria, synthetic biology, and iGEM. We also introduce them to basic ideas of sanitary techniques and tools used in a standard lab such as petri plates, agar, swabs etc. and how to layout an experiment; what is your hypothesis, results and conclusions? Once we discuss these basic concepts we allow the kids to take a swab of their hand and plate it on half of a petri dish. They then clean their hands with sanitizer and swab the other half of the petri dish. They then receive another petri dish where they can swab other places to find other ‘neat’ bacteria that may be lying around on the floor, counters, door knobs or wherever else they want (except up their nose, in their eyes, ears or mouth!). At this point and throughout the activity, interaction with the kids is key, as they always have stories or thoughts and experiences that are enlightening to share- even to us university students.



    Once we explain what incubation is, we allow kids to come in the next day and see all the different types of bacteria that may have grown on their petri plates and come up with conclusions from the results they have seen. We provide them with a record sheet where they are able to write down what they saw such as; morphology, colour, its surface and even elevation. To be able to interact with kids at such a young age and to introduce them to concepts which students are normally exposed to in higher grades, allows them to explore a part of their world that they never knew existed. Building curiosity at a basal level helps us connect with our community and bridge the gap towards making more informed decisions.

    The second activity for Grades 5-6 was called, “DNA Extraction from Your Cheeks”. This activity centers around the idea of DNA, where it is found, what it looks like and how every living organism contains very similar genomes, proteins and enzymes. There were four steps to this process, first to collect cheek cells, second to burst cells open to release DNA, third to separate DNA from proteins and debris and finally isolate the concentrated DNA. Kids obtain a cup of Gatorade containing a saline solution and swish the drink in their mouth for about a minute while gently chewing on their cheek cells. Then detergent is added to the test tube and meat tenderizer is added and the tube is inverted gently a couple of times. Cold rubbing alcohol is then added with a pipette which should allow the DNA to be visible. Then kids transfer the DNA into a PCR tube where they can hang it on a string to make a really neat necklace.



    Kids were keen and interested in these activities, especially learning about various different concepts that they had not yet been exposed to. “Who knew that DNA could come out of your own cheeks?” was the idea we wanted to pass along- that every living organism contains DNA. From bacteria to animals.

    Are you interested in doing these activities with kids around this age? Feel free to contact us at uwigem.outreach.hp@gmail.com. It is an inexpensive, interactive and fun way to have kids involved in genetics, microbiology and synthetic biology at a very early age.

    Introduction


    Synthetic Biology has been perceived as a field of science that has introduced tools, concepts and technologies which are sometimes sociologically and ethically insupportable. The non-scientific community has developed a stigma against the application of various synthetic biology technologies. The problem does not lie within the technology, but by an institution’s poorly executed strategy in educating the prospective end user about the relative benefit of its product. At times, the rate of technological advancements in the bioengineering industry surpasses the end-user’s ability to understand the necessity of the technology.

    The science behind these synthetic biology tools has been the current driver in instilling a sense of appeal and intrigue within the scientific community. However, it is critical that the institutions that develop these technologies educate the non-scientific community of the importance and benefit of these tools to help relieve these evolving stigmas.

    This year, the University of Waterloo’s Human Practices team’s focus was to develop a marketing strategy for their 2010 design project, the Staphiscope. The Staphiscope is an enhancement to the existing conventional plating methods that are used to detect Methicillin Resistant Staphylococus Aureus.

    The scope of the analysis includes:

    .
  • What is the selling point of the product? What differentiates the Staphiscope from what already exists and is accepted by the non-scientific community?
  • Does the concept of competition exist within synthetic biology? If so, how does an institution market the Staphiscope to optimize their opportunities for growth?
  • How can the marketing strategy approach be differentiated to ensure that both the scientific and non-scientific community are exposed to the relative benefits of the Staphiscope?
  • How do we channels the knowledge and learnings acquired within the synthetic biology industry and channel it to other stakeholders that will prospectively be impacted by the technology?

  • The purpose of the analysis is to ensure that the scientific industry understands the importance of bridging the scientific theory of a product to its economic feasibility. Moreover, it encourages institutions who participate in developing synthetic biology technologies to align their perception of a revolutionary design to what will be socially acknowledged by a non-scientific community.

    What is the Staphiscope?


    Methicilin resistant Staphylococcus aureus (MRSA) are bacteria whose presence has been quite problematic in terms of human pathogenic infections. Since its discovery in the 1880s, Staphylococcus aureus has been the known cause for several kinds of minor skin, and major post-surgical infections. Prior to 1940, mortality rates in relation to this pathogenic organism reached 80% (Deurenberg and Stobberingh, 2008.) The first wave of resistant S. aureus came two years after the introduction of penicillin for medicinal practice in 1940. In less than twenty years, most of the S. aureus strains known to man were unaffected by the antibiotic. In the late 1950s, a penicillinase-resistant penicillin was brought forth to the medicinal market; this was methicilin (Deurenberg and Stobberingh, 2008.) The bacterium's subsequent resistance to methicilin came two years after its introduction in 1959. The mecA gene responsible for methicillin resistance is also to blame for the organisms’ desensitization to several classes of antibiotics (Deurenberg and Stobberingh, 2008). This has led to the creation of the term: MRSA, now commonly used worldwide.

    While an MRSA infection is much like a S. aureus infection, the difference comes in the lack of sensitivity of the MRSA to several classes of antibiotics. This makes MRSA infections a serious threat in both health and economical aspects.

    The infection could be easily transferred directly (through regular skin-to-skin contact), as well as indirectly (through contamination of surfaces). The ease with which infection could occur, as well as the high mortality rate involved with the infection, make MRSA a serious threat to the health of patients worldwide (Durai et al., 2010.) There are only a few methods, which currently exit for MRSA screening. These are plating, liquid-broth inoculation, and PCR (polymerase chain reaction) assays. While these will be discussed in further detail later on in the report, it is important to note that these methods could be costly and time consuming, and could sometimes present incorrect results (Durai et al., 2010.)

    In 2010, the International Genetically Engineered team at the university of Waterloo had been working on a method which can be used in supplement to the already-existing ones for the detection of MRSA infections. It is a proof of concept for diagnosing the presence of Staphylococcus aureus in an infection site before it has had the chance to create an infection. This synthetic biology–based diagnostic method will take advantage of the quorum sensing mechanism of Staphylococcus aureus, and utilize Escherichia coli as the sensor and reporter. For more information with regards to the Design of the Staphiscope please see the University of Waterloo’s 2010 iGEM Page: https://2010.igem.org/Team:Waterloo

    Who are the “Competitors”?


    Treatment of an S. aureus infection is of extreme importance, as outcomes can range from simple pustules to death. Early detection and treatment of S. aureus carriers can reduce healthcare costs and greatly improve the health of the patient. There are only a few methods currently available to hospitals for the diagnosis of S. aureus infection. These methods are time consuming, expensive and, in some cases, not very reliable. The purpose of the Staphiscope is to provide the option of accelerating the method of detecting S. aureus, without compromising reliability. It will be a particularly useful tool in speeding up the conventional methods of serial plating.

    The following section analyzes the current products on the market and compares them to the Staphiscope.

    BD GeneOhm StaphSR



    Traditional culture methods for the detection of S. aureus are usually 2-3 days. The new BD GeneOhm™ StaphSR delivers a diagnosis in less than 2 hours, using rapid real-time PCR. Also, it can simultaneously detect and differentiate Methicillin-Resistant S. aureus and S. aureus from a positive result (blood culture). Currently under development are additional specimen claims – nasal and wound samples. Nasal claim will be able to determine colonization status and the wound claim will add to the rapid identification of positively infected patients. Obtaining positive results in a timely fashion aids clinicians in the prevention and control of infections.

    Method


    Specimen is prepared by transferring an aliquot of positive blood culture into a buffer team and then vortexed at high speed.

    Cell suspension is lysed (via vortex and centrifuge) and heated. Then the lysis is cooled. Molecular reagents are reconstituted and the sample undergoes PCR. Results are obtained in about 1 hour.

    GenoType MRSA

    Genotype MRSA uses DNA Strip Technology to identify both S. aureus and S. epidermidis cultures. Therefore, coagulase-positive and coagulase-negative staphylococci are differentiated. Simultaenously, the product can also detect Methicillin-Resistant S. aureus and S. aureus , which is incredibly important for therapeutic purposes. The test is performed from an overnight culture and guarantees results in only 4 hours.

    Method



    Culture is isolated from a sample or a primary culture is used.
    DNA is extracted via methods producing amplifiable DNA from bacteria (for example QIAamp DNA Mini Kit from Qiagen).
    Nucleic acids are selectively replicated in an amplification reaction. In the next step, the amplicons are chemically denatured, since detection on the DNA•STRIP® is done using single-stranded DNA. During the conjugate reaction, the specifically bound amplicon is marked with the enzyme alkaline phosphatase and is then made visible in a colorimetric detection reaction. In this way, a specific banding pattern develops on the DNA•STRIP®. Using a test-specific evaluation template, the test result can be read out quickly and clearly.

    Brilliance Agar



    Brilliance Agar is a chromogenic screening plate used for the diagnosis of Methicillin-Resistant S. aureus. It uses a novel chromogen to show a blue colour when Methicillin-Resistant S. aureus phosphatase activity. For sensitivity, it contains antibacterial compounds which inhibit growth of various competitor bacteria. This product has high sensitivity and specificity, which minimizes healthcare costs. However, results are presumptive and would need to be confirmed. Organisms with atypical resistance can give false negative results.

    Method


    Patient is inoculated using a screening swab or an isolated colony or liquid suspension is used. Sample is plated on Brilliance Agar. Plates are incubated at 37 ºC. Results are obtained in 18 hours. Methicillin-Resistant S. aureus grows as denim blue colonies.

    Competitive Analysis Matrix





    Rating Scale




    Methodology for Rating Scale


    The Competitive Analysis Matrix uses a format that divides the product’s market profile into several categories, providing a framework that ensures all issues are considered. Each category is scored in the course of the ratings process (using a numerical scoring system). Products are scored 1 through 27; those facing greater competitive threats would wind up with an overall low market profile score. Please note that ratings represent, in the end, an opinion. Please note, thorough assessment of each product’s market profile requires a broader framework, involving a comprehensive review of the product’s competitive position.

    Conclusions


    Based on a comparison and competitive analysis of the Staphiscope and the three major detection products on the market, the Staphiscope was found to have the highest market profile score. It uniquely scored highest in reliability and ease of use. Although all products on the market signify great innovation in the field, Staphiscope has great potential to gain market share.


    Porter’s Five Forces analysis


    Marketing Strategy


    Pitching the Staphiscope to a Research and Development Company When pitching the Staphiscope to the R&D industry, it is of paramount importance to establish its competitive advantage over traditional methods for S. aureus detection. To have a competitive advantage, a product or company must excel in at least one of the three following categories while remaining equal to its competitors in the others (Szarka, 2010):

  • Market access
  • Infrastructure
  • Technology

  • Market access refers to how easily the target demographic can get the product. Even a revolutionary technology can be hampered by a lack of market access. Infrastructure is related to whether or not a supply chain exists, as well as facilities for production and distribution. The third point, technology, is where the Staphiscope excels; its superior technology is what will separate it from competitors. Other selling points of the Staphiscope include its speed, efficiency, and room for expansion (could this technique be applied to other cases?). Conversely, there are also barriers that must be overcome when pitching to the R&D industry; namely, one must avoid falling prey to “not invented here” syndrome (Szarka, 2010). This term applies to the mindset some companies have of only trusting in-house innovation, and can be difficult to alter. Other barriers include the lacking of Staphiscope use on a commercial scale, and public perception regarding E. coli. While the latter issue can be combated via a public awareness campaign, the former is simply a fact of any innovative technology.
    Companies such as Amyris Biotechnologies and Codon Devices have attempted to commercialize in the field of synthetic biology. Their experiences provide valuable lessons that can applied to the Staphiscope (Wilan, 2005). The most relevant of these is that patent protection should be a serious concern when developing a novel technology, especially in such a burgeoning and competitive field. Consolidating IP ownership and control early is equally important, as doing so will prevent a lack of unified vision from stalling the Staphiscope’s progress. Of course, there are a plethora of patent and IP issues surrounding the field of synthetic biology that must be dealt with before or during the commercialization process. Chief amongst these is the scope of protection that can be provided to new technologies (Chugh Sakushyma, 2009). Additionally, looking for a pharmaceutical partner can help ease the transition into commercialization.
    It is important to realize that commercialization is a multi-year effort. As such, it can be beneficial to develop a commercialization plan (Office of Technology Transfer). This plan gives a general outline of what information the R&D industry will be looking for when it comes time to make a pitch. Details about market size and growth rates, predicted sales figures for the first five years, licensing agreements and more can all prove invaluable when attempting to bring a product to market. Preparedness in regards to this information can make the difference between a successful pitch and an unsuccessful one.
    In summary, pitching the Staphiscope to the R&D industry is a complex process that must be handled correctly to ensure its successful commercialization.

    How Do We Achieve Public Acceptance?


    For years, it has been believed that the prevalence of MRSA infections has resided within the walls of either a hospital or health care facility. Due to understated hygienic practices, a modified and relatively more virulent strain of Staphylococcus Aureus has also threatened several community based settings. In addition to Hospital Acquired MRSA, general health practitioners must also take into account the occurrence of community acquired MRSA. It is important to educate the public about the applications and relative benefit of the Staphiscope. Thus, there needs to be a channel of communication that allows for a transfer of knowledge between the scientific and non-scientific community.

    Who Do We Want To Educate?


    Given that MRSA may not only be spread within a hospital but also within the community, there are quite a few demographics that would gain value in understanding the benefit of the Staphiscope.

    Hospital Setting


    At least 2% of patients in hospitals or health-care facilities are likely to carry a strain of Staphylococcus Aureus that is resistant to antibiotics such as Methicillin. The following individuals are susceptible in contracting an MRSA infection:

  • Individuals who have weak immune systems
  • People receiving kidney dialysis or cancer treatments
  • Individuals who have been hospitalized or have had surgery over the past year

  • MRSA within the Community



    Patients who are discharged may have an inactive form of MRSA that remains colonized in their system. Thus, those who live within the community are still at risk of acquiring and suffering from antibiotic resistant Staph infections that are relatively more virulent. MRSA has been detected and acquired by healthy people in both institutionalized and individual based settings. The following individuals are susceptible in contracting MRSA in the community:

  • Day-care facilities or facilities in which equipment of personal items are shared
  • Military bases
  • Individuals who get tattoos


  • The Strategy


    In the field of synthetic biology, there is an unrecognized paradox that hinders the level of interdisciplinary communication between the scientific and non-scientific community. The stigmas built outside the realms of a scientific community grow at a greater rate than a scientist’s ability to answer the plethora of questions surrounding the regulation, safety and potentiality of these synthetic biology technologies. Another problem lies in a scientific institution’s inclination to address the ethical concerns surrounding their synthetic biology technology or process. Generally an individual who has not be previously exposed to the field, will construct an ethical judgement proceeding the phase where a company is about to commercialize their product. At this critical stage of a company’s product plan, stakeholders are reluctant in addressing these ethical concerns as it may discourage their ability to advance and innovate their existing technology. Regardless of the threats that these ethical judgments have previously imposed, there is a necessity in developing an approach in which the end result is an internationally renowned sense of public acceptance and support. “Without public support and understanding of research into synthetic biology, both funding and regulation are unlikely to support significant scientific advances” (Gaisser, et. al, 2009). To address this issue, an expert committee in Europe supported by the New and Emerging Science and Technology programme set out a roadmap that outlines the four interconnected attributes that will instil a sense of public acceptance within the non-scientific community. These four attributes are:

  • Scientific Milestones
  • Knowledge Transfer
  • Funding
  • Regulation


  • This roadmap outlines that without the implementation of a knowledge transfer strategy, there is limited confidence attaining in achievements under the other three key areas of the model. Scientific milestones would not be achievable without a sustained level of funding provided through other groups impacted by the prospective commercialization of these synthetic biology tools. Moreover, regulation of synthetic biology tools is influenced by the ethically themed perceptions created by both the scientific and non-scientific community.
    The knowledge transfer strategy would be an interdisciplinary model that would impact the following stakeholders:

  • Natural and Social Scientists
  • Engineers
  • Industry Representatives
  • Non-governmental organizations
  • Non-scientific community (ie. hospital staff, hospital patients and members within institutionalized settings)
  • Decision makers (ie. potential investors)
  • Funding Agencies


  • Knowledge Transfer Strategy



    In this context, knowledge transfer is the exchange of research knowledge between the institution producing the synthetic biology technology and their target end-user. The purpose of the knowledge transfer strategy is to develop a communication platform between all stakeholders to mitigate the unsourced perceptions, bias’ and stigmas against the field of synthetic biology. Moreover, it is better to develop an interdisciplinary team at the early stages of the technology development phases versus segregating the two communities until the technology is prospectively in its commercialization phase.

    The following are examples of methods that can be used by the synthetic biology industry in promoting tools such as the Staphiscope to its potential end-users (ie. individuals within hospitals and community facilities)

  • Development of an interdisciplinary network that consists of synthetic biologists, engineers, potential investors, and the general public
  • Sustainable dialogue between all stakeholders within the interdisciplinary network. This can be achieved through: Workshops that aim in exchanging information to individuals that will benefit from the application of the Staphiscope in either a hospital or community based setting
  • Educational materials that are specifically tailored to the different parties that could be impacted by the commercialization of the StaphiScope (ie. Hospital Microbiologists, Patients, and the General Public)
  • Incorporating the General Public and other stakeholders at the research phase of the technology development process. This results in a mutual benefit to both the institution as well as the end-user in that they are able to collaboratively discuss the ethical feasibility of the technology.
  • Use of knowledge broker- A knowledge broker is essentially an intermediary resource that assists in translating research knowledge to information that is comprehensible to a member that is not from the field of synthetic biology. An individual that has attained perceptions, knowledge and experiences from the scientific, business and social field is best suited to convey the importance of the Staphiscope to the stakeholders that have been listed above.
  • Partnerships between Synthetic Biology institutions and hospitals or other community based facilities.


  • Synthetic biologists must consider the importance of implementing an approach to help relieve the prospective stigmas that could potentially impact the relative success of their technology. The general public plays an influential role in the innovation capabilities of these synthetic biology technologies. Thus it is critical that these synthetic biology institutions involve the public and create awareness of their technologies at all stages of the research and development stage. Integrating a strategy that incorporates the exchange of knowledge is a fundamental leverage that would help create an aura of public acceptance and support all dimensions of the synthetic biology roadmap.

    Human Practices Commercialization Toolkit


    Following the Regional Jamboree, the Human Practices team began to develop the tools, templates and models that would assist a synthetic biology community and its associate stakeholders to understand the commercialization process. More importantly, our aim is to develop informational material that would achieve the integration of a knowledge transfer strategy in the field of synthetic biology. By streamlining the knowledge transfer strategy throughout each stage of the commercialization process, we are able to achieve a paralleled level of communication between the scientific and non-scientific community. Below is a sample of the toolkit our team has developed.

    The Commercialization Road Map


    The University of Waterloo Human Practices Team has devised a commercialization road map specific to the field of synthetic biology. The purpose of this road map is to outline the different stages of the technology development process. More importantly, it indicates what initiatives must be completed at each stage, who needs to be involved, and the strategies that can be utilized to attain the intended end-goal; A Scientific Milestone.

    The Knowledge Transfer Strategy Action Plan


    The University of Waterloo Human Practices Team has devised a knowledge transfer strategy to help parallel the level of communication between the scientific and non-scientific community. This document outlines the strategies that are currently being used or proposed at the University of Waterloo but can be easily used on a wider scale by the entire iGEM community. To view the knowledge transfer strategy plan, please click the link below.
    Knowledge Transfer Strategy

    Conclusion


    The purpose of this analysis was to understand the relative feasibility of a synthetic biology tool from the perceptions of a scientific and non-scientific community. When devising a marketing strategy, most companies define a technology’s commercial success by its appeal towards investors or its ability to enter a market heavily saturated by other established technologies. Given that most synthetic biology institutions are still at their preliminary phases in terms of commercialization, it is critical that their product is widely accepted and acknowledged by all disciplines that are impacted or will be potentially exposed to the technology.
    In the future we hope to take our research and methodologies and present them to the stakeholders discussed within the analysis. Our next steps are to identify institutions and facilities that would benefit from the use of the knowledge transfer strategy and develop sample activities or educational materials that can be used by these facilities to promote the Staphiscope.

    UNIVERSITY OF WATERLOO


    University of Waterloo was founded in 1957 and has grown to accommodate 30,000 undergraduate and graduate students, and has become Canada’s leading university in comprehensive learning. Also, the university has consistently been voted as the most innovative, most likely to produce the leaders of tomorrow, and best overall University in Canada for over 18 years (according to Maclean’s Magazine). Waterloo’s reputation is however based on its excellent and pioneering co-op program which offers students a balance of work and school on a per term basis, making it a unique learning experience. The city of Waterloo has recognized University of Waterloo and its students, by meeting its demands in terms of funding and involvement. The University has also opened up two new campuses; the pharmacy building, and the joint McMaster medical building in Kitchener, as well as the architecture building in Cambridge, contributing to not only the city of waterloo but the whole Grand River area.


    WATERLOO - KITCHENER COMMUNITY


    City of Waterloo mainly revolves around the two universities: University of Waterloo and Laurier University. Waterloo is surrounded by Kitchener and thus, the two cities are known as the twin cities, also referred to as Kitchener - Waterloo. The population of the city of Waterloo is always fluctuating due to temporary residents at Waterloo’s two universities. Total population in 2009 was recorded to be 121, 700; approximately 20,000 of which were temporary post-secondary students. Due to its small size, people in the past have tried to merge the two cities together but have been unsuccessful. As of today, both cities have their own identity and their own separate city governments.

  • SAFETY



    Laboratory Safety

    The Ribozyme Project is not expected to raise any research, public or environmental safety concerns other than those normally associated with Biosafety Level 2 organisms, such as Escherichia coli (DH5-alpha), which is classified as very low to moderate. The use of this project is primarily reserved for research and laboratory use, therefore, should not purposefully be exposed to the public or environment except after further testing in its specific applications (such as with particular fusion proteins). Furthermore, the basis of our project is to establish a self-excising sequence (ribozymes), which should limit the expression of any intervening sequences to the RNA level. If the intervening sequence were something of environmental or public relevance (such as antibiotic resistance), the experimental design indicates that the sequence will be removed and, thus, not expressed. This is a relevant contribution of the design in limiting expression to the RNA level, which eases environmental hazard concern upon the accidental release of a GMO containing this biobrick. Therefore, the new biobrick parts submitted should not raise any safety issues.


    The necessary facility, equipment and handling procedures associated with Level 2 Biosafety concerns were met:

    1.Pipetting aids
    2.Biosafety cabinets where applicable
    3.Laboratory separated from other activities
    4.Biohazard sign
    5.Proper safety and disposal equipment, including autoclave
    6.Personal protective equipment, worn only in the laboratory
    7.Screw-capped tubes and bottles
    8.Plastic disposable pasteur pipettes, when necessary



    All precautions with respect to recombinant DNA were observed:
    1.All waste was autoclaved before being thrown away.
    2.Researchers practiced aseptic technique and personal hygiene and safety precautions
    3.Procedures likely to generate aerosols are performed in a biosafety cabinet
    4.Bench surfaces were disinfected with ethanol.
    4.Potentially contaminated waste is separated from general waste


    Safety Questions


    1. Would the materials used in your project and/or your final product pose: The materials used in the lab are non toxic to health of individuals as well as to the environment. One of the major reagents that is used is GelRed which is used as a substitute for Ethidium Bromide. Gel Red is unable to penetrate into cells and so is a non-mutagenic agent. As well it has the same spectral characteristics as Ethidium Bromide and so has the same effectiveness of use. The project itself is safe even if released into the environment by design or accident since the part being expressed is the Green Fluorescent Protein (GFP). Unless the sequences are mutated, the project poses no risk.
    Please explain your responses (whether yes or no) to these questions.
    Specifically, are any parts or devices in your project associated with (or known to cause):

    - pathogenicity, infectivity, or toxicity? No
    - threats to environmental quality? No
    - security concerns? No
    The parts that are associated with the project this year are at the same level of risk as the any of the regular parts that already exist. All parts are constructed in an antibiotic containing backbone so that accidental release of will pose minimal risk to contaminating other bacterial populations.


    2.Under what biosafety provisions will / do you operate?
    a.Does your institution have its own biosafety rules and if so what are they? The University of Waterloo had a Bio-Safety plan in place to ensure the proper use to bio-hazardous materials in teaching and research at the university. A more detailed overview of their plans is outlined at the Bio-Safety Website
    b. Does your institution have an Institutional Biosafety Committee or equivalent group? If yes, have you discussed your project with them? The laboratories operating at the University of Waterloo have obtained permits from the Bio-Safety Committee in order to perform intended research. Since the Waterloo iGEM team performs all laboratory work in a parent lab under the guidance of the Masters and PhD students of that lab, the projects carried out in the lab are covered by the permits obtained by the parent lab.
    c. Will / did you receive any biosafety and/or lab training before beginning your project? If so, describe this training. All lab volunteers are required to take an online training to familiarize themselves with the Biosafety practices of the University of Waterloo. The training is followed up by a quiz ensuring proper understanding of the material. Upon completion of the training and quiz a hands- on lab training is provided under supervision of the parent lab’s PhD student. The hands-on training involves instruction of use of the appropriate equipment that is used in the lab, as well as how to maintain and discard materials in a safe manner.
    d. Does your country have national biosafety regulations or guidelines? If so, provide a link to them online if possible. Canada operates under the guidelines set up by the Public Health Agency of Canada. The Agency is the national authority on matters concerning biosafety and biosecurity. Risks to the public are reduced by standardizing controls over activities that involve human pathogenic agents, domestic or imported. While these guidelines are in place the current iGEM project does not involve work with any agents or materials that may pose a risk to humans. The link to the Public Health Agency of Canada is provided below: Public Health Agency of Canada
