GenCrispr eSpCas9 nuclease is a mutant form of Cas9 nuclease. Cas9 nuclease is an RNA-guided endonuclease that can catalyze cleavage of double stranded DNA. This kind of targeted nuclease is a powerful tool for genome editing with high precision. Cas9 protein forms a very stable ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component of the CRISPR/Cas9system. Compared with the wild type Cas9 nuclease, eSpCas9 reduces off-target effects by over 10-fold, while maintaining robust on-target genome editing efficiency. GenScript has developed a eSpCas9-N-NLS nuclease which contains a nuclear localization sequence (NLS) on the N-terminus of the protein to meet all the researchers’ requirements (e.g. in vitro cleavage assay, RNP complex transfection, and micro injection).
This is a basic protocol. The reagent concentrations, conditions, and parameters may need to be optimized.
1000 nM is equal to 160 ng/μL.
For laboratory research use only. Direct human use, including taking orally and injection and clinical use are forbidden.
