3-(4,5-Dimethylthiazolyl-2)-2,5-Diphenyl Tetrazolium Bromide, MP Biomedicals

Description

• Thiazolyl Blue Tetrazolium Blue (MTT) may be 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
