Luciferase and protein content measurements
The results of the corrected luciferase/total protein activity is displayed in figure 1. Unfortunately, all the strains grown at 25ºC and 30ºC showed no luciferase activity. We expect lysis of the cells did not work, due to a low amplitude of the sonicator. K115031 is left out here because it has such a high luciferase activity it interferes with the scale.

In figure 2 we displayed the 37ºC fold increase of luminescence / total protein over the 20ºC sample.

From this experiment we drew the conclusion that construct K115035 is the most probable construct for showing temperature induced switching behavior.

Growing 25ºC and 30ºC cultures (again)
Due to the failing of lysis of cultures grown at these temperatures, we've started new o/n growth of these cultures. New method of lysis will be the Fastprep machine.
