First lure sequence upstream of eGFP
This part is a off-target detecting platform for dCas9-ω. We put this part in a plasmid and transfer it into △rpoZ-MG1655, a strain of E.coli that was koncked out rpoZ. If dCas9-ω is binding to this lure 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 green fluorescence,which means dCas9-ωis off-target, else the weak promoter and the lack of rpoZ makes the reporter cannot express or just have a quite low expression level.
According to the refrence, the off-target rate of the lure sequence in this part is 0.08286%.
