PvuII has a High Fidelity version PvuII-HF® (NEB #R3151) High Fidelity (HF) Restriction Enzymes have 100% activity in CutSmart 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 de…

Having supplied restriction enzymes to the research community for over 40 years, NEB has earned the reputation of being the leader in enzyme technologies. Working continuously to be worthy of that distinction, NEB strives to develop enzymes of the highest purity and unparalleled quality.

Restriction Enzyme 

BbsI-HF has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10119525.  NEB is excited to announce that all reaction buffers are now BSA-free. NEB began switching their 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.

FastDigest® restriction enzymes are an advanced line of restriction enzymes for rapid DNA digestion. All FastDigest® enzymes are 100% active in the universal FastDigest® Green buffer and are able to digest DNA in 5-15 min. This enables any combination of restriction enzymes to mork simultaneously in one reaction tube and eliminates the need for sequential digestions. FastDigest® enzymes can be used to digest plasmid, genomica…

Restriction Enzymes Dpn I is an ideal enzyme for cloning and Southern blot analysis High purity enzyme preparation Includes 10X universal reaction buffer Glogos II Autorad Markers Luminescent peel-off stickers used for accurately marking and aligning autoradiographs. Easily affixed to plastic wrap or paper, these convenient markers emit low-level luminescence rather than radioactivity, making the Glogos II m…

The high-purity DpnI restriction enzyme is ideal for cloning and Southern blot analysis, and used for site-directed mutagenesis. Stringent quality control is achieved via pBluescript phagemid cloning assay. This assay tests the overall quality of the restriction enzyme used when cloning into the multiple cloning site of the pBluescript II phagemid vector.
