Cell Viability, Cell Proliferation, Cytotoxicity Assays (MTT, XTT, MTS)

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. For example, the MTT assay depends on the reduction of MTT by enzymes present in viable cells to form a blue formazan product that can be quantified by measuring the absorbance. The choice of assay may be based on the desired workflow and time required.
