DESCRIPTION
Cas9 nuclease, from Streptococcus pyogenes, is an RNA-guided endonuclease that catalyzes a site-specific cleavage of double stranded DNA. The cleavage occurs within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif). The PAM sequence must follow the targeted region on the opposite strand of the DNA with respect to the region complementary sgRNA sequence. Transfer of a custom-designed crRNA molecule for target gene together with tracrRNA and Cas9 protein will lead to a specific cleavage of target sequence in cells.

nCas9, a point mutant (D10A) of wild-type Cas9 nuclease, has a nick endonuclease activity. nCas9 nuclease contains a single nuclear localization sequence (NLS) at the C-terminus of the protein.

nCas9 nuclease is an optimized recombinant enzyme, which is expressed and purified from E.coli strain as 6xHis-tagged form at the N-terminal end.
