EnGen™ Spy Cas9 NLS NEB #M0646 is also available now.
We are excited to announce that all reaction buffers are now BSA-free. NEB began switching our BSA-containing reaction buffers in April 2021 to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. Find more details at www.neb.com/BSA-free.
Ideal for in vitro digestion of dsDNA
Compatible with EnGen® sgRNA Synthesis Kit, S. pyogenes (NEB #E3322S) and the EnGen Mutation Detection Kit (NEB #E3321S)
Cas9 Nuclease, 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 in vivo: Bacterial Adaptive Immunity
CRISPR loci in the bacterial genome are transcribed and processed into crRNA. Cas9 endonuclease complexed with a crRNA and separate tracrRNA cleaves foreign DNA containing a 20-nucleotide crRNA complementary sequence adjacent to the PAM sequence. (Figure not drawn to scale.)
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.
In vitro DNA cleavage using Cas9 Nuclease, S. pyogenes
Reactions were set up according to recommended conditions, and cleavage products were resolved on a 1% agarose TBE gel. Input DNA is PvuII-linearized pBR322 plasmid DNA.
Product Source
An E. coli strain that carries the cloned Cas9 gene from Streptococcus pyogenes
Reagents Supplied
The following reagents are supplied with this product:
If planning to use higher concentration Cas9 Nuclease, S. pyogenes (M0386T and M0386M) for in vitro digestion of DNA, the enzyme should be diluted to 1 µM using Diluent B (NEB #B8002S) prior to the reaction assembly.
