A high fidelity restriction endonuclease that recognizes the sequence GAAGAC(N)2. 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.
