3- (4,5-Dimethyl-2-thiazolyl-2)-2,5-diphenyl-tetrazolium bromide is used as a colorimetric metabolic activity indicator in cell viability assays. Thiazolyl Blue Tetrazolium Blue (MTT) is a dye used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

Description: Product is the lyophilized powder of human IgG and buffer salts. All blood products should be treated as potentially infectious. Source material from which this product was derived was found negative when tested in accordance with current FDA required tests. No known test methods can offer assurance that products derived from human blood will not transmit infectious agents. The total protein is determined using the Biuret procedure, with bovine albumin as the standard. Each vial is overfilled by approximately 5 percent so that a minimum of 500 mg of human IgG is obtained upon reconstitution.

Description: A modified tripeptide reversible protease inhibitor of trypsin-like proteases and some cysteine proteases including endoproteinase Lys-C, kallikrein, papain, thrombin, cathepsin B, cathepsins H and L, trypsin, calpain, trypsin and plasmin. Little to no inhibition is seen against pepsin, cathepsins A and D and alpha-chymotrypsin. When adjusted for molarity, all three salt forms are equally effective; however, the hydrochloride salt is usually less invasive in biological settings. Leupeptin, because of its aldehyde group, may act as a reducing agent and therefore interfere in protein determinations such as Lowry and, to a lesser extent, Bradford.
