Product Class: Restriction Endonuclease

EcoP15I
neb31 recombinant time saver 2site dil_A 37 65 Heat

We are excited to announce that all reaction buffers are now BSA-free. NEB began switching our BSA-containing reaction buffers in April 2021 to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. Find more details at www.neb.com/BSA-free.

Product Notes

  1. ATP is required for DNA cleavage. Efficient cleavage requires the presence of two inversely oriented recognition sites. A head to head orientation is preferred. The "head" of the sequence is defined as the dG at the 3´ end of the CAGCAG strand (top strand). Cleavage efficiency is also affected by the distance between the two sites.
  2. EcoP15I requires two copies of its recognition sequence for cleavage to occur, with limited cleavage on plasmids with a single site.
  3. Based on the stability of the enzyme in the reaction, incubations longer than 1 hr will not result in improved digestion, unless additional enzyme is added. Please refer to Restriction endonuclease survival in a reaction for more information regarding this topic.
  4. Requires two or more sites for cleavage. Please review the enzyme list and recommendations in the following table as well as the background information article.
  5. Not sensitive to CpG, dcm, or dam methylation.

FAQs & Troubleshooting

FAQs

  1. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  2. Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
  3. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
