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 (CutSmart^® 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 CutSmart Buffer
Time-Saver™ qualified for digestion in 5-15 minutes
Reduced star activity
Supplied with 1 vial of Gel Loading Dye, Purple (6X)

Product Information
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 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.

Product Source
An E. coli strain that carries the cloned and modified DraIII gene from Deinococcus radiophilus (ATCC 27603).
