Product Class: Restriction Endonuclease

BamHI-HF®
neb31 cloned at NEB recombinant engineered time saver dil_A 37 No

BamHI-HF has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10133983. Learn more.

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.

NEB high fidelity restriction endonuclease that recognizes the sequence G^GATC_C
Isoschizomers | Single Letter Code

Product Introduction

Not sensitive to dam, dcm or mammalian CpG methylation.

High-Fidelity (HF®) restriction enzymes have the same specificity as native enzymes, but have been engineered for significantly reduced star activity and performance in a single buffer (rCutSmart™ Buffer).  All HF-restriction enzymes come with Gel Loading Dye, Purple (6X).  Enjoy the enhanced performance and added value of our engineered enzymes at the same price as the native enzyme:

  • Engineered for improved performance
  • 100% activity in rCutSmart Buffer
  • Time-Saver™ qualified for digestion in 5-15 minutes
  • Reduced star activity
  • Supplied with 1 vial of Gel Loading Dye, Purple (6X)
  • Restriction Enzyme Cut Site: G/GATCC

FAQs & Troubleshooting

FAQs

  1. Is there a difference in cutting close to the ends between BamHI-HF and BamHI?
  2. Is there any difference in the methylation sensitivity between BamHI-HF and BamHI?
  3. What is the difference between BamHI-HF and BamHI?
  4. How does the level of star activity of BamHI-HF compare to BamHI?
  5. Why are there larger than expected bands after digestion with the BamHI-HF™ restriction enzyme?
  6. What does HF® refer to following the name of a restriction enzyme?
  7. When is star activity a concern?
  8. Why does the HF version of the enzyme have a different recommended buffer than the wild type enzyme?
  9. When should I choose the High Fidelity (HF®) version of the enzyme?
  10. How is the improvement in fidelity of HF restriction endonucleases quantitated?
  11. What is the Fidelity Index (FI)?
  12. Can the change in buffer preference of the HF enzyme be advantageous?
  13. Will the HF enzyme produce elevated star activity when used in a buffer other than the one recommended?
  14. What does it mean to be Time-Saver™ qualified?
  15. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  16. 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?
  17. Is Gel Loading Dye, Purple (6X) or Gel Loading Dye, Purple (6X), no SDS compatible with other DNA binding dyes such as SYBR® and GelRed™ during gel electrophoresis?
  18. Can Gel Loading Dye, Purple 6X (B7024) be stored in cold temperatures?
