Colorimetric cell viability, cell proliferation, cytotoxicity assays (MTT, XTT, MTS)

Colorimetric assays using tetrazolium salts like MTT, XTT, and MTS can be used to measure cell proliferation and cytotoxicity. Enzymes present in viable cells reduce a chromogenic reagent to form a colored product that can be quantified by measuring the absorbance.
