Tuesday, May 24
The reporter group decided on a few linkers to test in a fusion protein construct. These linkers are K243004 (4 amino acids), K105102 (10 amino acids) as well as the linker used in the Imperial College part, K316007. The reporters spent the rest of the time designing primers for PCR. We needed primers for the XylE part, the linker, the tev cleavage site and the GFP/flag tag complex of the Imperial College part, K316007, the CI repressor/RecA cleavage site, the LacZ part (J33210), the K243004 linker, and the K105012 linker.

The reporter group also began assembly of a construct featuring the XylE gene (with RBS) and a lac inducible promoter. This construct will be used to test the reporting system before the sensor system is created. Ben and Alex transformed the Plac and the XylE gene. The Plac part is R0010 and the XylE part is J33204.
Friday, May 27
The reporter group ran colony PCR on the created colonies then ran the results on a gel. The gel showed that the construct consisted of less than 500 base pairs, but should have been over 1100 base pairs. We think that only the lac inducible promoter showed up in our colonies. As a result of this set back, we will have to redo assembly next week.
