Keep track with what we did so far
(12.07.09)
- This first week of wetlab we have done the following things
- Transformed the plasmids with the LovTAP gene, generously sent by Dr. Sosnick's lab from Chicago universtiy, into competent E.Coli
- Designed the cloning strategy for cloning the LovTAP gene from its original vector to a iGEM vector+add an inducible promoter (LacI) (+RBS +term.)
- Orderd and received the primers needed for the PCR of LovTAP
- Designed the cloning strategy for inclusion of the LovTAP BioBrick with different reporting cassettes
- Transformed all the BioBricks that will be needed for the cloning strategies (c.f. notebook for more information about this parts) into competent E.Coli
- Fused the two BioBricks "LacI" and "term"
- Digested the LovTAP PCR products and RBS part
Project Abstract
Recent discoveries of photoreceptors in many organisms gave us insights about a possible interest to use light responsive genetic tools in synthetic biology. More precisely, the final goal of our project is to induce a gene expression change, more specifically to turn on/off a gene, in a living organism in response to a light stimulus.
We will use light sensitive DNA binding proteins, or light sensitive proteins that activate DNA binding proteins to transduce light input in a chosen output, for example reporter gene like GFP, RFP. The genetic circuits allowing us to measure the activity and the responsiveness of the light sensitive proteins are already designed, whereas parts and biobricks required to engineer these circuits are still in formation.
If we demonstrate that this kind of light induced gene switch tool works in vivo, it would show that easier and faster tools could be used in several field of biology. It would induce more localized, more precise (time resolution) and drastically faster genetic changes than the current used tools, which will then allow research to evolve even better.
