WebbThe MTT calorimetric assay determines the ability of viable cells to convert a soluble tetrazolium salt [3– (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) into an insoluble formazan precipitate. Tetrazolium salts accept electrons from oxidized substrates or appropriate enzymes, such as NADH and NADPH.
