SalI

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.

Product Information

SalI has a High Fidelity version SalI-HF^® (NEB #R3138).

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 minutes 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

Product Notes
1. This enzyme has shown to have lower activity on some supercoiled plasmids, with more than 1 unit required to digest 1 μg plasmid DNA. For complete digestion of 1 μg of plasmid DNA please follow our recommended digestion protocol.
2. Cleavage of mammalian genomic DNA is blocked by CpGmethylation.
