A serine proteinase used to inactivate RNAse and DNAse in RNA and DNA isolation protocols. Useful in the study of membrane and protein structure. Proteinase K is a highly active protease (MW 28,500 Da) isolated from the fungus Tritirachium album . The enzyme exhibits broad specificity on…

Protease which cleaves specifically at the -COOH side of arginie and lysine. TPCK-treated Trypsin is a serine endopeptidate Trypsin is treated with TPCK to inactivate any remaining chymotryptic activity This type of trypsin is modified by acetyltion of the sigma-amino groups of lysine…

Also known as 5-Bromo-4-Chloro-3-Indolyl Phosphate. A widely used chromogenic substrate for alkaline phosphatase in enzyme-linked assay systems. BCIP may be used alone, or may act in a coupled reaction with NBT. Upon cleavage of the phosphate group from the molecule, BCIP forms a bright blue,…

Inhibits chymotrypsin, kallikrein, plasmin, thrombin, trypsin and other related thrombolytic enzymes. Less toxic substitute for PMSF. Specific and irreversible inhibitor of serine proteases. Synonym: 4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride pK_b: 9.19 (Predicted) …

Also known as 5-Bromo-4-Chloro-3-indolyl-β-D-Glucopyranoside. A substrate for Beta-glucosidase that renders an intense indigo-blue chromophore (615 nm) upon enzymatic action. Used as an indicatior-probe in histochemistry and in culture media to detect beta-Glucosidase positive organisms.

Also known as 4,-5-Dihydro-2-(6-hydroxyl-2-benzo-thiazoyl)-4-thiazole-carboxylic acid. Used with firefly luciterase in bioluminiscence for the determination of ATP.
