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.
