XTT (2,3-Bis-(2-Methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide, disodium salt) is a tetrazolium derivative used widely in cell viability and proliferation testing. The material is readily reduced in viable cells to a highly water-soluble orange colored product (λ= 475 nm). Applications of the reagent include studies of antifungal susceptibility, drug sensitivity of cells, parasitic nematode viability and tumor cell cytotoxicity.
