New England Biolabs, Inc. Esp3I – 300 units
A Type IIS restriction endonuclease that recognizes the sequence CGTCTCN^NNNN_....
New England Biolabs, Inc. SalI – 2000 units
A restriction endonuclease that recognizes the sequence G^TCGA_C.
New England Biolabs, Inc. Exonuclease V (RecBCD) – 5000 units
Exonuclease V, a RecBCD complex from E. coli has several different enzyme activities, including an ATP-dependent single-stranded DNA endonuclease activity, ss- and ds- DNA exonuclease activity. The hydrolysis in each case is bi-directional (from both the 3' and 5' ends) and processive, producing oligonucleotides. All Exonuclease V activities have divalent cation requirements. Mg2+ is required for the exonuclease activity, while Ca2+ inhibits the exonuclease activity and allows double-stranded DNA unwinding (helicase activity) without hydrolysis.
New England Biolabs, Inc. EagI-HF – 2500 units
A high fidelity restriction endonuclease that recognizes the sequence C^GGCC_G. 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.
New England Biolabs, Inc. Blunt/TA Ligase Master Mix – 50 reactions
Blunt/TA Ligase Master Mix is a ready-to-use solution of T4 DNA Ligase, proprietary ligation enhancer, and optimized reaction buffer. This master mix is specifically formulated to improve ligation and transformation of both blunt-end and single-base overhang substrates. The master mix format simplifies reaction set-up, ensures an optimized ratio of enzyme and buffer components, and yields robust, rapid ligation of all types of DNA ends using a short incubation time at room temperature. No thawing is necessary as it remains liquid during storage at -20C. Ligations for subcloning can be carried out in small volumes with low DNA concentrations, allowing users to conserve precious DNA samples and directly transform many strains of chemically competent E. coli without dilution.
New England Biolabs, Inc. PmlI – 10000 units
A restriction endonuclease that recognizes the sequence CAC_^GTG.
New England Biolabs, Inc. SacI-HF – 10000 units

Apexbio Technology LLC EZ Cap Nuc-mScarlet Probe mRNA (m1Ψ) 5x1mg (1mg/mL)
Nuc-mScarlet mRNA encodes a fusion protein combining a nuclear localization signal (Nucleus-targeting signal) with the fluorescent protein mScarlet By fusing mScarlet with a nuclear localization signal it enables the monitoring of dynamic processes inside the nucleus in living cells in real-time Nuc-mScarlet exhibits high photostability and brightness making it particularly suitable for long-term imaging experiments Moreover the spectral properties of mScarlet are compatible with other fluorescent proteins such as GFP facilitating multiplex labeling experiments EZ Cap Nuc-mScarlet Probe mRNA (m1 ) is provided at 1 mg/mL specifically designed for nuclear-targeted expression of red fluorescent protein labels This mRNA is synthesized through co-transcriptional capping resulting in a Cap 1 structure The incorporation of m1 modifications poly(A) tail significantly enhances mRNA stability and lifetime both in vitro and in vivo
New England Biolabs, Inc. BssSI-v2 – 200 units
BssSI-v2 is an engineered and improved version of BssSI that recognizes the sequence VC^TCGAGB. BssSI-v2 is an engineered and improved version of BssSI. (NEB uses the designation "v2" or "HF" in the name to indicate engineered enzymes.)
