Depositor Comments

pCbh-3xFLAG-NLS-SpCas9-HF1-NLS (without U6-sgRNA coding sequence).
SpCas9-HF1 subcloned in the same plasmid backbone and tailored to identically possess the same NLS and FLAG tags at their termini like the eSpCas9 (without U6-sgRNA coding sequence) (Addgene #92354).
The expression level of SpCas9-HF1 is higher from this than from the original plasmid (VP12; Addgene #72247).

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).
