Faqs & Tech Tips

FAQs

  1. Do degenerate recognition sites need to be palindromic?
  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. 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?
  6. Why is my Restriction Enzyme not cutting DNA?
  7. Why do I see a DNA smear on an agarose gel after a restriction digest?
  8. Why do I see additional DNA bands on my gel after a restriction digest?
  9. How many nucleotides do I have to add adjacent to the RE recognition site in order to get efficient cutting?
