    Specificité
    Activity test
    Cas9 site-specific digestion:
    We used in vitro digestion of a linearized plasmid to determine the activity of the Cas9 nuclease. It is a sensitive assay for GenCrispr Cas9 quality control. The linearized plasmid containing the target site:
    (CATCATTGGAAAACGTTCTT)
    can be digested with gRNA:
    (CAUCAUUGGAAAACGUUCUUGUUUUAGAGCUAGAAAUAGCAAGUUAAAAUAAGGCUAGUCCGUUAUCAACUUGAAAAAGUGGCACCGAGUCGGUGCUUUUUUUU)
    and GenCrispr Cas9. Two cleavage DNA fragments (812 bp and 1898 bp) are determined by agarose gel electrophoresis. A 20 μL reaction in 1xCas9 Nuclease Reaction Buffer containing 160 ng linearized plasmid, 40 nM gRNA and 20 nM GenCrispr Cas9 for 2 hours at 37 °C results in 90 % digestion of linearized plasmid as determined by agarose gel electrophoresis.
    Attributs du produit
    GenCrispr Cas9 Nuclease is produced by expression in an E. colistrain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes without nuclear localization signal (NLS).

    Sujet
    GenCrispr Cas9 Nuclease is the recombinant Streptococcus pyogenes Cas9 (wt) protein purified from E. coli that 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 produces DNA breaks within 3 bases from the NGG PAM (Protospacer Adjacent Motif). With GenCrispr Cas9 nuclease, customers can screen for highly efficient gRNA in vitro using DNA cleavage assays. The high purity Cas9 protein can also be used for antibody production.
