pCbh-3xFLAG-NLS-HeFm1SpCas9-NLS (without U6-sgRNA coding sequence).
Highly enhanced Fidelity nuclease variant HeFm1SpCas9 contains mutations from both eSpCas9 (1.1) and SpCas9-HF1.
HeFSpCas9s exhibits activity with spectacularly increased specificity specifically for those targets that are met with higher off-target propensity by eSpCas9 (1.1) and SpCas9-HF1.
The lack of sgRNA expression cassette allows for easy testing of various SpCas9 variants with the same sgRNA expressed from a separate plasmid (e.g. pmCherry_gRNA, Addgene# #80457).
