Reporter: We would like to further characterize our reporter system, especially with regards to the optimal buffer solution that a sample should be placed in. Afterwards, we could test a variety of substrates with lacZ as well as other genes to determine what the optimal reporting molecule is. Also, seeing if we can develop a smaller and cheaper version of the setup is an option we would like to explore.


qRT-PCR: On the RT-PCR side of the promoter search there are a few more points to test. Although we have identified a potential candidate gene, up-regulated in the presence of NA's, the next step is to test if the response observed can be duplicated with a general stress, such as hydrogen peroxide. Another thing to test is the specificity of the observed response, to see if structurally variant naphthenic acids can elicit the same response.


"Sensory Element Fishing": For this side of the project we need to optimize the interaction between the streptavidin beads and our biotinylated compound. To do this we are going to have to find a way to efficiently separate our compound from the solution that it is currently in without damaging the biotinylated compound. After this is done we will be able to perform the IPs that we have envisaged.


Chassis: In terms of tools, further chaacterization of the HspA70/RbcS2 promoter and algal luciferase is needed. The addiiton of a few more selectable markers suitable for use in algae. Ultimately, we also want to finish the construction and screening of chloroplast and nuclear promoter libararies in Dunaliella tertiolecta.


Prototype: During the development of our electrochemical reporter system we spent a lot of time thinking about what hardware could be used and found out that a potentiostat is the best option. A potentiostat is the electronic hardware needed to control the three electrode system used to measure the data in our experiments. It keeps the working electrode at a constant potential with respect to the reference electrode by adjusting and measuring the current between the working electrode and counter electrode. We obtained our data using a professional lab grade potentiostat, but we also spent some time looking into how they are designed and managed to built our own prototype. While it is built on a breadboard and is bigger than the potentiostat we used for the measurements, it is a valid proof of concept that potentiostats can be built using electrical circuit components no more complicated than an operational amplifier.
The ultimate goal would be to construct a fully functional prototype which could send the collected data directly to a computer. However, building a prototype was a lower priority compared to conducting the actual experiments and we weren’t able to finish it over the summer.
