| Description |
GenCRISPR™ Ultra NLS-Cas9-GMP is utilized for
CRISPR gene editing applications. The Cas9 nuclease forms a stable
ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component. With the
help of nuclear localization signal (NLS) expressed with the Cas9 nuclease, the
RNP complex enters the nucleus and cleaves the target gene. When compared with a
plasmid-based delivery system, the RNP delivery system has been observed to
increase the on-target gene editing efficiency and decrease off-target effects. |
| Selection Guide |
GenScript provides both wild-type and mutant
Cas9 nucleases in GMP Grade* for selection based on your specific downstream

materials for Cell, Gene, and Tissue-Based Products and are manufactured under
the standards listed below:
- § USP <1043>. Ancillary
materials for Cell, Gene and Tissue-engineered products.
- § ICH Q7 Good Manufacturing Practice Guide for Active Pharmaceutical
Ingredients
- § NMPA: Technical guidelines for pharmaceutical research and
evaluation of immune cell therapy products
- § Guideline and procedure specified in Chinese Pharmacopeia.
