Notes

  1. BsrGI is an isoschizomer of Bsp1407I.

FAQs

  1. Did BsrGI replace Bsp1407I?
  2. What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
  3. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  4. How can I access the old NEBuffer Activity Chart?
  5. Why is my Restriction Enzyme not cutting DNA?
  6. Why do I see a DNA smear on an agarose gel after a restriction digest?
  7. Why do I see additional DNA bands on my gel after a restriction digest?
  8. How many nucleotides do I have to add adjacent to the RE recognition site in order to get efficient cutting?

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. Further information regarding NEB product quality can be found here.
  • 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.
