Used for measurement of cell division and proliferation. 3-(4,5-Dimethylthiazolyl-2)-2,5-Diphenyl Tetrazolium Bromide, MP Biomedicals (MTT) is a histochemical/cytochemical reagent. It is converted to water-insoluble MTT-formazan of a dark blue color by mi

Thiazolyl Blue Tetrazolium Blue (MTT) may be used in measurement of cell proliferation. It 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 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 570nm
  • MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems
