網頁Description. 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 … 網頁2024年9月3日 · The Cas9 nickase (nCas9), which differs from Cas9 protein in a single point mutation (D10A or H840A), can also cleave single-stranded target sites recognized by sgRNA. When repair systems fail to repair the DSBs introduced by Cas9, which causes bacterial cell death, it can be used for genome editing instead of Cas9 [ 17 ].
