Cat: CAS09N


CRISPR/Cas9 is an adaptive immune defense system formed by bacteria and archaea during their long-term evolution. The CRISPR/Cas9 system integrates fragments of invading phage and plasmid DNA into the CRISPR sequence and utilizes corresponding CRISPR RNAs (crRNAs) to guide the degradation of homologous sequences by Cas9 proteins, thereby providing immunity. The artificially modified Cas9/sgRNA system uses sgRNA (short guide RNA) to guide Cas9 proteins to recognize and cleave double stranded DNA with sgRNA targets, which can be used for gene knockout and precise DNA editing operations. The Cas9 nucleic acid Endonuclease provided by this product can enable the protein to enter the nucleus for Genome editing by adding a nuclear localization signal (NLS) to the N-terminal of the protein. This product is a pure protein system to avoid plasmid or virus interference during CRISPR gene knockout.
