GenCrispr Cas9 Nuclease

GenCrispr Cas9 Nuclease is the recombinant Streptococcus pyogenes Cas9 (wt) protein purified from E. coli and can be used for genome editing by inducing site-specific double stranded breaks in double stranded DNA. Cas9 protein forms a very stable ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component of the CRISPR/Cas9 system. The RNP complex recognizes the target site by matching gRNA with the genomic DNA sequence and leads to DNA breaks within 3 bases from the NGG PAM (Protospacer Adjacent Motif). With GenCrispr Cas9 nuclease, customers can screen highly efficient gRNA using in vitro DNA cleavage assays. It could be a powerful tool for gene editing.

Product Source : GenCrispr Cas9 Nuclease is produced by expression in an E. coli strain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes without nuclear localization signal (NLS).

With this Cas9 Nuclease, you can:

1. Screening for highly efficient and specific targeting gRNAs by in vitro DNA cleavage using Cas9 Nuclease from S. pyogenes ( please find the detailed protocol in the product manual ).
2. Highly purified Cas9 antigen could be used for specific antibody production.
