Restriction Enzymes
New England Biolabs, Inc. AleI-v2 – 2500 units
AleI-v2 is an engineered and improved version of AleI that recognizes the sequence CACNN^NNGTG.
New England Biolabs, Inc. MluCI – 5000 units
A restriction endonuclease that recognizes the sequence ^AATT_.
New England Biolabs, Inc. Nt.BsmAI – 500 units
A restriction endonuclease that recognizes the sequence GTCTCN^N.
New England Biolabs, Inc. RNase Inhibitor, Human Placenta – 2000 units
RNase Inhibitor, Human Placenta is a recombinant human placental protein which specifically inhibits ribonucleases (RNases) A, B and C. It is not effective against RNase 1, RNase T1, S1 Nuclease, RNase H or RNase from Aspergillus. In addition, no inhibition of polymerase activity is observed when RNase Inhibitor, Human Placenta is used with Taq DNA Polymerase, AMV or M-MuLV Reverse Transcriptases, or Phage RNA Polymerases (SP6, T7, or T3). The 50 kDa protein inhibits RNases by binding noncovalently in a 1:1 ratio with an association constant greater than 1014.
New England Biolabs, Inc. BsiWI-HF – 1500 units
A high fidelity restriction endonuclease that recognizes the sequence C^GTACG. 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.
Electron Microscopy Sciences TEM Specimen Supports Molybdenum 1000 µm
We have extended our range of TEM grid materials to include four types, which are now available in Molybdenum. The new products are manufactured using a process known as chemical ʽmilling' (etching) instead of the more familiar technique of ʽelectroforming' (deposition) that is used in the manufacture of copper, nickel and gold products. Molybdenum is used principally in applications where it's high temperature, hardness, expansion of coefficient and corrosion resistance characteristics are considered important. The material which is used has a purity of 99.9%.

New England Biolabs, Inc. WarmStart Nt.BstNBI-1000 u
WarmStart Nt.BstNBI is a site specific nicking endonuclease cloned fromBacillus Stereothermophilus. Restriction Enzyme Cut Site GAGTC(4/-5). It is formulated with a reversibly-bound aptamer which inhibits its nicking activity at temperatures below 40C. WarmStart Nt.BstNBI cleaves only one strand of DNA on a double-stranded DNA substrate. The nicking endonuclease catalyzes a single strand break 4 bases beyond the 3side of the recognition sequence.
