Product Class: Restriction Endonuclease

BsgI
neb31 cloned at NEB recombinant time saver 2site dil_B 37 65 Heat

BsgI has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10201941. Learn more.

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

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.

Product Introduction

  • Time-Saver™ qualified for digestion in 5-15 minutes
  • 100% activity in rCutSmart™ Buffer (over 210 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.

  • Restriction Enzyme Cut Site: GTGCAG(16/14)

FAQs & Troubleshooting

FAQs

  1. Why doesn't BsgI cut well?
  2. What is the activity of BsgI at 25°C?
  3. Are there known sequence errors at the recognition site in a database?
  4. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  5. I tested your restriction enzyme on the substrate DNA recommended by NEB, and it appears to be active, however it does not digest my DNA. What could be the reason?
  6. Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
  7. Does BsgI require SAM for activity?
  8. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
