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.

  1. Why isn't SapI cutting?
  2. What sequence does SapI recognize?
  3. Are all sites compatible for ligation?
  4. Is extended digestion of SapI recommended?
  5. Is SapI used for any special techniques?
  6. What is the activity of SapI at 25°C?
  7. My restriction enzyme used to be available at a lower concentration. Why does it now come at a higher concentration of 10,000 u/ml?
  8. What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
  9. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  10. How can I access the old NEBuffer Activity Chart?
  11. How can I access the old Double Digest Finder?
  12. 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?
