<h1>Week 1: June 6 - June 11</h1>
<h1>Week 1: June 6 - June 11</h1>
In the first week we began constructing basic reporter DNA constructs that have various combinations of promoters and genes. The mix-and-matching of promoters and genes was done using the LR reaction following the Gateway protocol. Our promoters included TRE, minCMV, Hef1a, Hefl1a-LacO, and our genes included eYFP, mKate, and eBFP2. Transformed and inoculated colonies from the LR reactions and performed restriction digests. Approximately half of the LR reactions were successful and became DNA parts that we could use later on.

Overview

Here you can see what we did weekly in the lab!

Week 1: June 6 - June 11

In the first week we began constructing basic reporter DNA constructs that have various combinations of promoters and genes. The mix-and-matching of promoters and genes was done using the LR reaction following the Gateway protocol. Our promoters included TRE, minCMV, Hef1a, Hefl1a-LacO, and our genes included eYFP, mKate, and eBFP2. Transformed and inoculated colonies from the LR reactions and performed restriction digests. Approximately half of the LR reactions were successful and became DNA parts that we could use later on.

Comments:

pEXPR_2-3_Tre:LexAVP16 and pEXPR_3-4_minCMV-7xMnt1:eYFP are being entirely redone.

pEXPR_2-3_Tre:LexAVP16 (post-miniprep) was lost. pEXPR_3-4_minCMV-7xMnt1:eYFP LR was unsuccessful (no bacteria grew).

LR and transformation will be done on Saturday. Miniprep and restriction mapping will be done on Sunday

Week 2: June 12 - June 18

In the second week we attempted midipreps instead of minipreps of our available cell stocks. Midipreps were unsuccessful, likely due to centrifuge limitations. LR reactions to generate more usable promoter-gene pair parts continued, expanding to include the CI434-VP16, LexA-VP16, and Mnt-VP16 genes, whose expressed proteins activate the appropriate corresponding minCMV promoters. Most of the LRs done were not successful, reason unknown at this time.

Highlights:

~10:30 AM: Miniprep of pDEST23-ccdB commenced and completed. DNA concentrations of the two samples were 175 and 310 ng/uL

From Gel Below:
A and C show the entry vector, B failed as well, D seems to have worked. There is uncut DNA around 7000 bp, but the other bands seem correct. D will be sent for sequencing.

Midipreps were done by Kenneth and Tyler for sequenced verified constructs, 2-3_Tre:LacI-Krab, 3-4_minCMV 1xCI434:eYFP, and 3-4_Hef1ALac0:eYFP. Unfortunately DNA yields were low, as shown in the table below, so minipreps will be performed tomorrow, June 16, 2011.

Conclusion: pDEST12 appears to be growing slowly in all cases, as does pDEST45. pDEST23 grows at the rate typically expected by Gateway reaction standards while pDEST34 grows at a rate much faster than these standards. Corroborated in Weiss lab?

Week 3: June 20 - June 24

In the third week we continued expanding our library of usable DNA parts by creating more combinations of genes and promoters using the LR reaction.

Week 4: June 27 - July 1

In the fourth week we implemented a color-coded box system in our -20 freezer to accommodate for the growing need of organization of the growing number of DNA parts. We began learning and using the Gibson reaction to create the gene part AVPR2-TEVs-GV16, which is expressed to produce a vasopressin receptor bound to Gal4-VP16 by a TEV sequence that can be recognized by the TEV Protease. Gibson reaction results were not great, and it appeared that our AVPR2 DNA was not of sufficient quality, so we re-PCRed the AVPR2 DNA segment.

Week 5: July 4 - July 10

We began looking into using the Goldengate assembly method, but two gene elements contained a cut site that needed to be mutated out. We performed Site-Directed Mutagenesis using the Lightning Kit in the hopes of mutating out the cut site, but results were not successful due to mishandling during the protocol, so the procedure was set to be repeated. Gibson assembly of AVPR2-TEVs-GV16 continues as we re-PCRed the AVPR2 DNA segment and re-run the entire Gibson protocol, picking 20 colonies in a determined attempt to obtain a successful result.

Week 6: July 11 - July 17

In the sixth week we continued re-attemping previous failures using modified protocols or higher quality DNA in hopes of obtaining successful reactions. We also began looking at Cadherins and the possibility of using them as a clumping mechanism for mammalian cells. In order to visualize Cadherins, we needed some sort of fluorescent color, so construction of NCadherin-EGFP (NCadherin is one of many types of cadherin) began. DNA for NCad-EGFP was ordered, but needed to be in a format such that we could LR react it with the different promoters we have. This is done by attaching attB sites to flank the NCad-EGFP gene and then performing the BP reaction, which generates LR reaction-compatible parts. PCR of the attB sites was successful. By this week we have also begun work with mammalian cell cultures. To explore the limitless possibilities of synthetic biology, a few of us took it upon themselves to look into other interesting gene components, such as the Caspase gene and the FF4 tag.

Week 7: July 18 - July 24

Part of the team worked on creating protocols for a robot liquid handler to run the usual lab reactions that we run. We are hoping that the robot can replace us and do our liquid-related lab work for us. Various dry test runs were done. We transfected various DNA parts that we have into Hek293 cells, and results show that most of our DNA works. We investigated the TRE-rtTA3 system as well as the UAS-Gal4 system. Both seemed to be functional.

Week 8: July 25 - July 31

This week we underwent a momentous drive to create more LRs. A large list of promoter-gene pairs was conceived of and we began to run through LR reactions in somewhat of a factory manner. This occupied much of our time. We also received and prepared DNA parts from Elowitz's group in Caltech. We also got trained on using the FACS machine and began to get quantitative data on our transfections.

Week 9: August 1 - August 7

In the ninth week we did a lot of internal re-organization to increase our overall efficiency in work. This involved re-organizing an internal wiki that we use for management of our available DNA as well as a log of transfections needed to be done. Lots of samples were FACS-ed, generating lots of results that we can make graphs out of. Many of our parts were successfully characterized.

Week 10: August 8 - August 14

Computer simulations of the Notch-Delta interactions were presented in our group this week, and we became convinced of the possibility of creating self-patterning mammalian cells. On the DNA side of things, we are trying to create more and more DNA using miniprep, because midipreps have for some reason not been successful for us or the 2010 iGEM team. On the transfection side, a lot of new DNA parts were transfected, observed under the microscope, and FACS-ed to quantify their effect/behavior.

Week 11: August 15 - August 21

In our experimental attempt to characterize the Notch-Delta interaction, we used co-culture of CHO and Hek293 cells as well as stable cell lines of Notch-containing and Delta-containing cells from Elowitz to observe the trans-activation of Notch by Delta. Other experiments using CHO cells, which are more difficult to transfect than Hek293 using Lipofectamine, were carried out to observe the behavior of CHO transfected cells.

Week 12: August 22 - Later

Stay tuned!

Week 12

September 1

Grant: Inoculations of the aforementioned LR constructs.

August 29

Charles - CHLRs see CH notebook. H, HL, T, U and delta-ff4, H and T for ncad-2a-eyfp. inoculated propagations for HLNcad2Aeyfp, UASNcad2aeyfp, and Tre:delta.

August 28

Grant: Restarted LR reactions of 9 of the constructs listed on the Workflow (only the pEXPR_12_Hef1a-LacO_Notch-CI434-VP16 construct succeeded, possibly due to incubation time for LR reactions). Started PCRs for Tango constructs using new padding for TEV cut site.

August 25

Divya: Won. (See Personal Notebook for details).

August 23

Charles - FACS Kens 50 50 and 80 20 Hek TRE-delta senders and CHO receivers. FACS was clean. Cells were all healthy. Lowered voltage of DAPI channel from 300 to 240 to move blank cells basal fluorescence to the bottom left corner. Laser was on, everything went according to plan. Preliminary results look promising, with increasing dox for each coculture, there was increasing FITC channel signal. Preliminary results suggest that our delta works.

August 22

Charles - FACS of Kens coculture stuff. Ambiguous results.
