Product Class: Restriction Endonuclease

BfuCI

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.

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.
  • 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. BfuCI is an isoschizomer of Sau3AI.
  1. Is BfuCI activity sensitive to dam, dcm or mammalian CpG methylation?
  2. How many base pairs should be added at the end of a PCR primer next to the BfuCI recognition site to guarantee that BfuCI will cut properly?
  3. Does BfuCI have any isoschizomers?
  4. What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
  5. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  6. How can I access the old NEBuffer Activity Chart?
  7. How can I access the old Double Digest Finder?
  8. 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?
