This product was discontinued on 10/01/2016 Catalog # Size Concentration Price Qty Categories: Discontinued Products Product Information FAQs & Tech Tips Protocols & Manuals Quality & Safety Description Related Products References Legal Information Properties and Usage Notes Description Cas9 Nuclease NLS, S. pyogenes, is an RNA-guided endonuclease that catalyzes site-specific cleavage of double stranded DNA. The location of the break is within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif) (1). The PAM sequence, NGG, must follow the targeted region on the opposite strand of the DNA with respect to the region complementary sgRNA sequence. Cas9 Nuclease NLS, S. pyogenes contains a single Simian virus 40 (SV40) T antigen nuclear localization sequence (NLS) on the C terminus of the protein. Cas9 nuclease, S. pyogenes, complexed with an sgRNA Cleavage occurs three nucleotides upstream of the PAM sequence (shown in red). sgRNAs are complimentary to the strand of DNA opposite of the PAM. Product Source An E. coli strain that carries the cloned Cas9 gene from Streptococcus pyogenes with a C-terminal Simian virus 40 (SV40) nuclear localization signal (NLS) and a N-terminal 6XHis tag.

Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page. Further information regarding NEB product quality can be found here. Endonuclease Activity (Nicking): The product is tested in a reaction containing a supercoiled DNA substrate. After incubation for 4 hours the percent converted to the nicked form is determined by agarose gel electrophoresis. Exonuclease Activity (Radioactivity Release): The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides. Functional Test (Cas9 Nuclease, Targeted Digestion): Cas9 Nuclease is tested in a reaction containing target DNA and guide RNA. The percent digested target DNA is determined by agarose gel electrophoresis. Non-Specific DNase Activity (16 hour): The product is tested for non-specific nuclease degradation in a reaction containing a DNA substrate. After incubation for 16 hours there is no detectable degradation of the DNA substrate as determined by agarose gel electrophoresis. Protein Purity (SDS-PAGE): The physical purity is assessed by comparing contaminating protein bands in a concentrated sample to the protein of interest band in a sample of known dilution. The purity is determined by SDS-PAGE. RNase Assay (Extended Digestion): The product is tested in a reaction containing a fluorescent RNA substrate. After incubation >90% of the substrate RNA remains intact as determined by gel electrophoresis.
