The GenCRISPR™ Ultra Cas9 product line provides customers with a selection of research use, GMP preclinical and GMP compliant Cas9 nucleases. The Cas9 protein can be formed with the guide RNA into a ribonucleoprotien (RNP) complex. The use of an RNP complex to perform gene editing has been shown to reduce the challenges encountered with other CRISPR gene editing techniques such as viral and plasmid delivery. Challenges include off-target effects, cell viability and trascprition/translational challenges. GenCRISPR™ Ultra Cas9 is produced by expression in an E. coli strain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes with an N-terminal nuclear localization signal (NLS). |
For laboratory research use only. Direct human use, including taking orally and injection and clinical use are forbidden.
