cloned at NEB recombinant neb31 2site dil_C 37 65 Heat CpG

We are excited to announce that we are in the process of switching all reaction buffers to be BSA-free. Beginning April 2021, we will be gradually transitioning to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. All information on the website has been updated to reflect this change. Find more details at www.neb.com/BSA-free.

NEB restriction endonuclease that recognizes the sequence CG^GWC_CG

Having supplied restriction enzymes to the research community for over 45 years, NEB has earned the reputation of being the leader in enzyme technologies.  Working continuously to be worthy of that distinction, NEB strives to develop enzyme of the highest purity and unparalleled quality. 

  • 100% activity in rCutSmart Buffer (over 215 enzymes are available in the same buffer) allowing for easier double digests
  • Requires two or more sites for cleavage. Please review the enzyme list and recommendations in the following table as well as the background information article.
