SAM now included in enzyme formulation – no longer supplied as a separate vial.

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

NEB restriction endonuclease that recognizes the sequence TCCRACNNNNNNNNNNNNNNNNNN_NN^
  • Time-Saver™ qualified for digestion in 5-15 minutes
  • 100% activity in rCutSmart Buffer (over 215 enzymes are available in the same buffer) allowing for easier double digests
  • Type IIS restriction enzymes recognize asymmetric DNA sequences and cleave outside of their recognition sequence
  • 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.
  • Cut Site: TCCRAC(20/18)
