Product Introduction
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)
- Restriction Enzyme Cut Site: G/AATTC

Product Information
Description
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.

FAQs & Troubleshooting
FAQs
- What does HF® refer to following the name of a restriction enzyme?
- Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
- I tested your restriction enzyme on the substrate DNA recommended by NEB, and it appears to be active, however it does not digest my DNA. What could be the reason?
- Is Gel Loading Dye, Purple (6X) or Gel Loading Dye, Purple (6X), no SDS compatible with other DNA binding dyes such as SYBR® and GelRed™ during gel electrophoresis?
- Can Gel Loading Dye, Purple 6X (B7024) be stored in cold temperatures?
- Which NEB restriction enzymes are supplied with Gel Loading Dye, Purple (6X)?
- Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
- Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
