Product Notes

  1. BaeI cleaves DNA substrates twice to excise its recognition site generating a 28 base-pair fragment with 5 base 3´ overhangs.
  2. BaeI was found to cut at its defined cleavage site as well as one base pair further from its recognition site.
  3. Blocked by some combinations of overlapping CpG methylation.

FAQs & Troubleshooting

FAQs

  1. Does BaeI have any special requirements?
  2. Does BaeI cleave DNA twice?
  3. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  4. 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?
  5. Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
  6. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
  7. In an effort to standardize reaction conditions, the recommended incubation temperature has changed for ApaI (NEB #R0114), BaeI (NEB #R0613), BsrDI (NEB #R0574) and SmaI (NEB #R0141). Which incubation temperature should I use?
  8. Are certain restriction enzymes more active at higher incubation temperatures than what is recommended?
