A: EcoRV cleaves to leave a ligatable blunt end in the tetracycline resistance gene of pBR322. EcoRV can be used in conjunction with NEB's LITMUS Vectors to add sticky ends to blunt-ended fragments. Q: Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? 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: Which NEB restriction enzymes are supplied with Gel Loading Dye, Purple (6X)? A: All HF-restriction enzymes and most NEB non-HF restriction enzymes are supplied with Gel Loading Dye, Purple (6X). The non-HF restriction enzymes that come supplied with purple dye are: AatII AsiSI BsmBI-v2 EagI MboI NlaIII PvuI SmaI Acil AvrII BspHI EcoRI MboII NotI RsaI SpeI AfeI BamHI BsrGI EcoRV MluI NspI SacI StuI AflII BbsI ClaI Esp3I FseI MseI PacI SacII AgeI BglII DdeI HaeIII MspI PciI SalI XbaI AluI BsaI DpnI HindIII NcoI PmeI SapI XhoI ApaI BseYI DpnII HpaI NdeI PsiI-v2 SfaNI XmaI ApeKI BsiWI DraI KpnI NheI PstI SfiI XmnI AscI * All HF restriction enzymes are also supplied with Gel Loading Dye, Purple (6X) Q: Is this enzyme sensitive to dam, dcm or mammalian CpG methylation? A: Yes. This enzyme cannot cut recognition sites in mammalian gDNA that are impaired by some combinations of overlapping 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. Q: Can Gel Loading Dye, Purple 6X (B7024) be stored in cold temperatures? A: The recommended storage temperature for Gel Loading Dye, Purple 6X, is room temperature (25°C). Commonly, the SDS may precipitate out of solution when the dye is stored on cold temperatures. This slight precipitate can be dissipated by letting the vial sit at room temperature for an hour, or warming gently for 10 minutes. Mix the vial a few times before use, to bring the solution back to homogeneity.
