A: NEBuffer Set (r1.1, r2.1, r3.1 & rCutSmart) contains recombinant Albumin (NEB #B9200) while NEBuffer Set (1.1, 2.1, 3.1 & CutSmart) contains BSA (NEB #B9000). Choose NEBuffer Set (r1.1, r2.2, r3.1 & rCutSmart) when you want to avoid BSA in the reaction buffer. 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.
