Target transcription activating unit upstream of RFP

This part is a on-target detecting platform for dCas9-ω. We put this part in a plasmid and transfer it into E.coli, which was knocked out rpoZ. For convenience, we called it △rpoZ-MG1655. If dCas9-ω is binding to target sequence, the submit Omega fused to dCas9 C-terminal can activate the expression of reporter by recruiting the RNAP holoenzyme and the cell would emit red fluorescence,which means dCas9-ωis on-target, else the weak promoter and the lack of rpoZ makes the reporter cannot express or just have a quite low expression level.
