Depositor Comments

We have also generated a version of this backbone with the core EF1a promoter driving the expression of KRAB-dCas9. We advise users to test both backbones in their cell type of interest. In our experience this backbone yields better knockdown in liver and pancreatic beta cells. Please visit for bioRxiv preprint.

We have also made available plasmids to be used as negative controls, which contain non-human genome target sequences (BFP or EGFP). Please see Addgene #118161, #118162, #118163 and #118164.
There is a third BsmBI site in the promoter region, which does not have an impact on the GoldenGate cloning. We recommend using the provided cloning protocol.

Note: Plasmid contains a N1396S mutation in dCas9. This mutation is not known to affect plasmid function.
