Construct for testing CRISPRi sgRNA suppression on fluorescence protein production

This construct is to test if sgRNA works in vivo to form a complex with dCas9, and suppress fluorescent protein (GFP) levels. It also aims to provide a baseline of fluorescence and suppressed fluorescence level.


This construct consists of an sgRNA for GFP expressed under a pBAD promoter and constitutively expressed GFP and a constitutively expressed dCas9 expression construct (BBa_K3017069).

By using an inducible promoter, we can compare the GFP level before and after turning on the arabinose-inducible pBAD promoter, thus evaluating the suppression effect caused by CRISPRi (brought about by the dCas9-sgRNA complex). The unsuppressed GFP level (before arabinose induction) also gives us a figure of how the GFP expression level would be affected when it is co-expressed with a dCas9 protein.
