Quorum Sensing Fluorescence Reporting Device
This composite part is used as the reporter of the quorum sensing device. It consists a Plux promotor and BBa_K3594009, a sfGFP gene. When the concentration of the signal molecule-LuxR-AHL reaches threshold, the bacteria start to commit suicide and at the same time, emit large amount of fluorescence.
In our project, we made the following changes to the above experiment:
pSHS6_pSB1C3_pTac_LuxR_plux_sfGFP: constructed by Gibson assembly T4 Ligation: pTac_LuxR_plux_sfGFP(~3.6Kb)and pSB1C3 backbone(~2Kb) This plasmid is used to test if LuxR and plux promoter work well.
Verification of LuxR and Plux
If the fluorescence value in the tube increases with time, and the fluorescence value in the tube with IPTG and atc is higher than no inducer or only one inducer, it proves that the bacteria emit fluorescence after reaching the threshold, therefore the experiment is successful.
