sgRNA(spacer J23101-GFP)-spacer J23101-GFP

We added a spacer sequence and a NGG site closely before the promoter(BBa_J23101 ). This spacer sequence can be recognized by the sgRNA we designed to direct dCas9. Once dCas9 binds with the spacer sequence, the expression of GFP will be repressed.We have submitted the sgRNA part (BBa_K2611000) and spacer-GFP part(BBa_K2611001). In this composite part, we linked them together.We observed positive colonies transformed with this part under a stereo fluorescence microscope.Green fluorescence was observed.(Fig.1) Besides,we also mearsured fluorescent intensity of bacteria (transformed with BBa_K2611010) solutions. (Fig.2)Compared with the NC, transformated bacteria solutions' fluorescence intensity/OD are much higher, which indicates GFP was expressed successfully in our transformated bacteria.
