2009 DNA Distribution quality control
The UNIPV-Pavia iGEM team sequenced T9002 part and found that it was completely confirmed, while iGEM QC results classified it as "inconsistent". DNA was resuspended from well 9A, kit plate 2, transformed in TOP10 E. coli and amplified inoculating a single colony from the grown LB agar plate in LB medium. Finally DNA has been miniprepped from the grown culture and sent to a BMR Genomics (Padova, Italy) for sequencing.

Experimental measurements The Brown iGEM team conducted tests on this part in the summer of 2007. The results are depicted in the graphs below.

The first graph indicates that until a critical point is reached, increasing AHL concentration does increase GFP output. This is most easily noticeable between the concentrations of 20 nM, after which point the amount of GFP produced by cells begins to decrease. This may be due to one of two things: AHL quenches the signal from GFP, or too much AHL disrupts the cell's functions in a way that either kills it or prevents it from making as much GFP. This second hypothesis is partially confirmed by the second graph, which shows that adding more than 20 nM AHL causes a decline in cell density. On each graph, the different colored lines represent different time points after AHL was added to the cells. They are 4 hours, 5 hours, etc.
