    This enzyme has transitioned to an improved new buffer system. Visit NEBCutSmart.com for further details.
     
    The new and current Double Digest Finder and current Activity/Performance Chart for the CutSmart buffer system are available. The previous version of the Double Digest Finder, as well as the previous Version of Activity/Performance Chart that use the former buffer system, are still available for your convenience.

    Description

    PvuI has a High Fidelity version PvuI-HF® (NEB #R3150).

    High Fidelity (HF®) Restriction Enzymes have 100% activity in CutSmart® Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver™ qualified and can therefore cut substrate DNA in 5-15 minutes with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.

    Quality Control

    Quality Control Assays

    The following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
    • Endonuclease Activity (Nicking):
      The product is tested in a reaction containing a supercoiled DNA substrate. After incubation for 4 hours the percent converted to the nicked form is determined by agarose gel electrophoresis.
    • Exonuclease Activity (Radioactivity Release):
      The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides.
    • Ligation and Recutting (Terminal Integrity):
      After an over-digestion of DNA with a restriction endonuclease the percentage of the DNA fragments ligated with T4 DNA ligase and the percentage that can be recut are determined by agarose gel electrophoresis.
    • Non-Specific DNase Activity (16 hour):
      The product is tested for non-specific nuclease degradation in a reaction containing a DNA substrate. After incubation for 16 hours there is no detectable degradation of the DNA substrate as determined by agarose gel electrophoresis.

    Notes

    1. Cleavage of mammalian genomic DNA is blocked by CpG methylation.

    1. Is PvuI a Time-Saver™ Qualified enzyme?
    2. Is PvuI activity sensitive to dam, dcm or mammalian CpG methylation?
    3. How many base pairs should be added at the end of a PCR primer after the PvuI recognition site to guarantee that PvuI will cut properly?
    4. Does PvuI have any neoschizomers?
    5. What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
    6. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
    7. How can I access the old NEBuffer Activity Chart?
    8. How can I access the old Double Digest Finder?
    9. My restriction enzyme used to work well in the old NEBuffer but the new Performance chart indicates it has lower activity even though the only difference is the addition of BSA and removal of DTT to the new buffers. Why?
