NheI has a High Fidelity version NheI-HF® (NEB #R3131).

High Fidelity (HF) Restriction Enzymes have 100% activity in CutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver qualified and can therefore cut substrate DNA in 5-15 minutes with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.
Product Source
An E. coli strain that carries the NheI gene from Neisseria mucosa heidelbergensis (ATCC 25999).

Notes
  • Cleaves to leave a 5´ CTAG extension which can be efficiently ligated to DNA fragments generated by AvrII, SpeI or XbaI.
  • Inhibited by salt concentrations > 100 mM.
  • This enzyme has shown to have lower activity on some supercoiled plasmids, with more than 1 unit required to digest 1 μg plasmid DNA. For complete digestion of 1 μg of plasmid DNA please follow our recommended digestion protocol.
  • Blocked by some combinations of overlapping CpG methylation.
