Description
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
