Presently, NEB supplies more than 200 restriction enzymes, over 120 of which are available in recombinant form.

Q5® Site-Directed Mutagenesis Kit enables rapid, site-specific mutagenesis of double-stranded plasmid DNA in less than 2 hours. The kit utilizes the robust Q5 Hot Start High-Fidelity DNA Polymerase along with custom mutagenic primers to create insertions, deletions and substitutions in a wide variety of plasmids. After PCR, the amplified material is added directly to a unique Kinase-Ligase-DpnI (KLD) enzyme mix for rapid, roo…

Rapid, sensitive and precise dye-based qPCR detection and quantitation of target DNA and cDNA sequences

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.

The New England Biolabs Magnetic mRNA Isolation Kit is designed to isolate intact poly(A)+ RNA from cells and tissue without requiring phenol or other organic solvents. The technology is based on the coupling of Oligo d(T)25 to 1 μm paramagnetic beads which is then used as the solid support for the direct binding of poly(A)+ RNA. Thus, the procedure permits the manual processing of multiple samples and can be adapted for autom…

The LunaScript® RT SuperMix Kit is optimized for cDNA synthesis in a two-step RT-qPCR workflow.

Purifies up to 100 µg of high quality total RNA from multiple sample types - using only one kit

Quickly and easily purify DNA from agarose gels with high yields.

For the extraction of HMW DNA from a variety of tissues, bacteria and other samples (yeast, insect, amphibian)

Restriction Enzyme 

Rapid, sensitive, and precise probe-based qPCR detection and quantitation of target RNA targets.

T7 Endonuclease I recognizes and cleaves non-perfectly matched DNA, cruciform DNA structures, Holliday structures or junctions, heteroduplex DNA and more slowly, nicked double-stranded DNA.

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.

A number of proprietary plasmids are digested to completion with appropriate restriction enzymes to yield 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 0.5-10.0 kilobases (kb). The 3.0 kb fragment has increased intensity to serve as a reference band. The approximate mass of DNA in each of the bands is provided (assuming a 0.5 μg load) f…
