Aims and background for testing our Quorum Sensing construct
In our first experimental set-up, we wanted to test whether our Quorum Sensing construct (further referred to as pIR) works on its own, and induces a pLux promotor to enhance trancription. The testing construct , which was used, consists of a pLux promoter and the gene for the green fluorescence protein. Therefore, it is expected that without Quorum Sensing construct no fluorescence occur.
For this purpose SCS1 E.coli cells were transformed with 1) pIR alone, 2) alone, and 3) pIR and J37032 together. The first one is the negative control. Without any GFP gene inside the cells they should not fluorescence. The second one should show no fluorescence as the promoter needs to be activated by Quorum Sensing or only to a small degree due to leakiness of the promoter. The third one should show low fluorescence at low cell density and high fluorescence at high cell density.
