The resolution is at the single nucleotide level.Īn E. The percent degradation is determined by capillary electrophoresis and peak analysis. Restriction Enzyme Competitor Study: Nuclease ContaminationĮcoRI, NotI, and BamHI from multiple suppliers were tested in reactions containing a fluorescent labeled single stranded, double stranded blunt, 3'overhang or 5' overhang containing oligonucleotides.

Examples of nuclease contamination studies for some of our HF restriction enzymes are shown below. NEB extensively performs quality controls on all standard and high-fidelity (HF) restriction enzymes. 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. 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. HF enzymes also exhibit dramatically reduced star activity. High Fidelity (HF) Restriction Enzymes have 100% activity in rCutSmart Buffer single-buffer simplicity means more straightforward and streamlined sample processing.
