Can I digest longer? A: NEB's Time-Saver™ enzymes have the benefit of working fast (5-15 minutes), but are also designed and qualified to withstand overnight digestions without degradation of DNA. Q: Is this enzyme sensitive to dam, dcm or mammalian CpG methylation? A: No. This enzyme is not sensitive to dam, dcm, or mammalian CpG methylation. For up-to-date information about methylation sensitivities, please visit Dam-Dcm and CpG Methylation or REBASE. Q: Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers? A: NEB is excited to announce that we have switched BSA-containing reaction buffers (NEBuffer 1.1, 2.1, 3.1 and CutSmart® Buffer) to Recombinant Albumin-containing buffers (NEBuffer r1.1, r2.1, r3.1 and rCutSmart™ Buffer). We are also in the process of moving all restriction enzyme formulations to contain rAlbumin. We feel that moving away from animal-containing products is a step in the right direction and are able to offer this enhancement at the same price.
