GenCrispr NLS-Cas9-D10A Nickase is a mutation form of Cas9 Nuclease.

DescriptionGenCrispr NLS-Cas9-D10A Nickase is a mutation 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 nuclease cleaves the double strand DNA generating two break sites based on its two active domains. NLS-Cas9-D10A Nickase is a mutation form of Cas9 Nuclease which makes one active domain deactivated, thus it can only cut one single strand DNA that is complementary to the guide-RNA, producing one single strand cut. Combined with two different gRNA, NLS-Cas9-D10A Nickase produces two cut sites respectively and causes a double strand break. Compared with the wild type Cas9 nuclease, the two-gRNA guided cleavage can significantly reduce the off target effects.Product Source: GenCripsr NLS-Cas9-D10A Nickase is highly purified mutant proteins expressed in an E. coli strain carrying a plasmid encoding the mutated Cas9 gene from Streptococcus pyogenes.Key features:DNA-free: no external DNA added to system.High cleavage efficiency: NLS ensures the efficient entry of Cas9 protein into nuclei.Low off target: Double gRNA-guided cleavage and transient expression of Cas9 nuclease.Time-saving: no need for transcription and translation.With this Cas9 Nuclease, you can:Screening the highly efficient and specific targeting gRNAs using in vitro DNA cleavage.In vivo gene editing combined with specific gRNA by electroporation or injection.Note1000 nM is equal to 160 ng/ul.產(chǎn)品屬性Storage & StabilityGenCrispr NLS-Cas9-D10A Nickase is supplied with 1X storage buffer (10 mM Tris, 300 mM NaCl,0.1 mM EDTA, 1 mM DTT, 50% Glycerol pH7.4 at 25°C).
