• Store desiccated at 4°C

XTT reagent is a tetrazolium derivative used widely in cell viability and proliferation testing. This is readily reduced in viable cells to a highly water-soluble orange colored product. Applications of the reagent include studies of antifungal susceptibility, drug sensitivity of cells, parasitic nematode viability and tumor cell cytotoxicity.
