Product Class: Restriction Endonuclease

PvuI-HF®
neb31 cloned at NEB recombinant engineered time saver dil_B 37 No CpG

PvuI-HF has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10128368. 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 CG_AT^CG
Isoschizomers | Single Letter Code

Product Introduction

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: CGAT/CG
Catalog # Size Concentration
R3150S 500.0 units 20000 units/ml
R3150L 2500.0 units 20000 units/ml

  2. How should I stop my restriction digest?
  3. How stable is a particular restriction enzyme?
  4. When should I choose the HF version of the enzyme?
  5. When is star activity a concern?
  6. How should I set up a restriction digest?
  7. I don't see any cleavage after my restriction digest. What factors can interfere with cleavage?
  8. How can I generate a restriction enzyme site map for my sequence?
  9. What information is available in the Restriction Enzyme Database (REBASE)?
  10. Is extended digestion (incubation times > 1 hour) recommended?
  11. Do degenerate recognition sites need to be palindromic?
  12. What does HF® refer to following the name of a restriction enzyme?
  13. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  14. Can Gel Loading Dye, Purple 6X (B7024) be stored in cold temperatures?
  15. 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?
  16. What does it mean to be Time-Saver™ qualified?
  17. Which NEB restriction enzymes are supplied with Gel Loading Dye, Purple (6X)?
