SpCas9 Nuclease
SpCas9 Nuclease is an sgRNA-guided DNA endonuclease. In the presence of a PAM (proto-spacer adjacent motif) sequence in the target DNA, Cas9 Nuclease can specifically cleave the target double-stranded DNA under the guidance of sgRNA, creating blunt-end double-strand breaks. more

Product Description
Cas9 Nuclease (SpCas9), derived from the S. pyogenes strain, is an sgRNA-guided DNA endonuclease that cleaves double-stranded DNA. In the presence of a PAM (proto-spacer adjacent motif) sequence in the target DNA, Cas9 Nuclease can specifically cut the target double-stranded DNA under the guidance of sgRNA, creating blunt-end double-strand breaks. The PAM sequence is essential for Cas9 to recognize and cleave the target DNA, with the cleavage site located within the target sequence, 3 base pairs away from the PAM region. Cas9 Nuclease can also be applied in experiments such as in vitro target DNA cleavage and cloning of specific fragments.
