Sigma Aldrich Fine Chemicals Biosciences Nuclease P1 from Penicillium citrinum, 54576-84-0, MFCD00131010, 1VL
Lyophilized powder, ≥200 units/mg protein (E1%/280, 3′-5′-Phosphodiesterase), Synonym: Endonuclease P1. Nuclease P1 from Penicillium citrinum has been used in a study to assess crystal structures using ammonium sulphate or polyethylene glycol 4000 as a precipitating agent. It has also been used in a study to investigate a method for the direct sequence analysis 20-25 nucleotides from the terinini of 5′ or 3′ end group labeled RNA. Nuclease P1 is used to improve the sensitivity of a 32P-labeling method for the detection of DNA adducts.
Integrated DNA Technologies Inc Alt-R S.p. HiFi Cas9 Nuclease V3, 500 µg
Alt-R S.p. HiFi Cas9 Nuclease V3, 500 µg
New England Biolabs, Inc. HiFi Taq DNA Ligase – 50 reactions
An optimized blend of a thermostable DNA Ligase and a proprietary additive, HiFi Taq DNA Ligase efficiently seals nicks in DNA with unmatched high fidelity. The formation of a phosphodiester bond between juxtaposed 5 phosphate and 3 hydroxyl termini of two adjacent oligonucleotides that are hybridized to a complementary target DNA is enhanced in the improved reaction buffer and mismatch ligation is dramatically reduced. The improved formulation allows higher resolution discrimination between ligation donors and acceptors, enabling precise detection of SNPs and other allele variants. HiFi Taq DNA Ligase is active at elevated temperatures (37-75C). Please note that HiFi Taq DNA Ligase is intended for use in molecular diagnostics applications that depend on high fidelity nick ligation. It is not a substitute for T4 DNA ligase and is not suitable for cloning applications or adapter ligation/NGS library prep.
ILEX LIFE SCIENCES LLC Ilex Life Sciences L-Asparaginase, E. coli Enzyme, Bioactive, 500 IU
Our high-purity, bioactive L-Asparaginase enzyme is purified from E. coli ASI.357. Purity: greater than 96%. Formulation: Lyophilized with no additives. Summary: L-Asparaginase is an enzyme that depletes L-Asparagine, an important nutrient for cancer cells, resulting in cancer/tumor cell starvation. The rationale behind asparaginase is that it takes advantage of the fact that acute lymphoblastic leukemia cells and some other suspected tumor cells are unable to synthesize the non-essential amino acid asparagine, whereas normal cells are able to make their own asparagine; thus leukemic cells depend on circulating asparagine. Asparaginase, however, catalyzes the conversion of L-asparagine to aspartic acid and ammonia. This deprives the leukemic cell of circulating asparagine, which leads to cell death. Synonyms: L-ASNase, L-asparagine amidohydrolase, ansA.
