High-Fidelity (HF®) restriction enzymes have the same specificity as native enzymes, but have been engineered for significantly reduced star activity and performance in a single buffer (rCutSmart Buffer).  All HF-restriction enzymes come with Gel Loading Dye, Purple (6X).  Enjoy the enhanced performance and added value of our engineered enzymes at the same price as the native enzyme:

  • Engineered for improved performance

  • 100% activity in rCutSmart Buffer

  • Time-Saver™

    qualified for digestion in 5-15 minutes

  • Reduced star activity

  • Supplied with 1 vial of Gel Loading Dye, Purple (6X)

  • Cut Site: A/AGCTT

High Fidelity (HF) Restriction Enzymes have 100% activity in rCutSmart 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 some of our HF restriction enzymes are shown below.

Restriction Enzyme Competitor Study: Nuclease Contamination


EcoRI, 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. The percent degradation is determined by capillary electrophoresis and peak analysis. The resolution is at the single nucleotide level.
