Revision as of 09:57, 6 August 2007
This year's [http://www.ccbi.cam.ac.uk/iGEM2007 Cambridge iGEM team], made up of five physical scientists with a biological bent and six biologists who want to try something a bit different, has been working since the start of July to get to grips with Synthetic Biology, and then to push its frontiers. After extensive brainstorming, we have decided to work on three projects to add to the capabilities of the Registry.
The first strand of our research is the construction of one or more well-characterised PoPS amplifiers, based on a number of protein activators and cognate inducible promoters from a number of E. coli phages investigated by other researchers. At present we are integrating the six promoter sequences and three activator sequences into plasmids; we will then carry out double transformations to generate and characterise the 18 different combinations.
