BclI-HF

We are excited to announce that we are in the process of switching all reaction buffers to be BSA-free. Beginning April 2021, we will be gradually transitioning to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. All information on the website has been updated to reflect this change. Find more details at www.neb.com/BSA-free.

Isoschizomers | Single Letter Code | Pronunciation:

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: T/GATCA

Product Information

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.

Product Source

An E. coli strain that carries the cloned and modified BclI gene from Bacillus caldolyticus (A. Atkinson).

Product Notes
1. BclI-HF has the same specificity as BclI (NEB #R0160), but it has been engineered for reduced star activity.
2. Cleaves to leave a 5´ GATC extension which can be efficiently ligated to DNA fragments generated by BamHI, BglII, MboI, Sau3AI and BstYI.
3. This enzyme is blocked by dam methylation. More information can be found at Dam-Dcm and CpG Methylation.
