ApoI-HF has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10177930. Learn more.
We are excited to announce that all reaction buffers are now BSA-free. NEB began switching our BSA-containing reaction buffers in April 2021 to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. Find more details at www.neb.com/BSA-free.
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:
An E. coli strain that carries the cloned and modified ApoI gene from Arthrobacter protophormiae (C. Polisson).
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.
