Description:
??
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 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.
NEB
extensively performs quality controls on all standard and high-fidelity(HF?) restriction enzymes. Examples of nuclease contamination studies for someof our HF restriction enzymes are shown below.
Restriction Enzyme Competitor Study: Nuclease Contamination
EcoRI, NotI, and BamHI from multiple suppliers were tested in reactionscontaining a fluorescent labeled single stranded, double stranded blunt,3’overhang or 5’ overhang containing oligonucleotides. The percent degradationis determined by capillary electrophoresis and peak analysis. The resolution isat the single nucleotide level.

Notes:
NheI-HF? has the same specificity as NheI (
NEB
#R0131), but it has been engineered for reduced star activity.Cleaves to leave a 5? CTAG extension which can be efficiently ligated to DNA fragments generated by AvrII, SpeI or XbaI.Activity inhibited by salt concentrations > 100 mM.
