Pcons2-rbs-lacI-Ter-Plac-rbs-luxI-Ter-Pcons2-rbs-luxR-Ter-Prlux-rbs-rfp-rbs-luxI-Ter
Plasmid in positive feedback verification: Pcons2-rbs-lacI-Ter-Plac-rbs-luxI-Ter-Pcons2-rbs-luxR-Ter-Prlux-rbs-rfp-rbs-luxI-Ter It is a positive feedback plasmid using luxI as key to feedback. Introducing IPTG will produce rfp and luxI, and luxI will work back to enhance production of rfp.
As is shown in the picture, plasmid with “LuxI-T”(purple) shows higher fluorescence intensity than the control(blue), so this kind of plasmid can be more efficient than the control, however, it is not as efficient as the plasmid with “LuxR-LuxI-T”(Yellow).
