4-[3-(4-iodophenyl)-2-(2,4-dinitrophenyl)-2H-5-tetrazolio]-1,3-benzenedisulfonate sodium salt (IPB) have found application in clinical assays and cell proliferation assays that are based on a spectrophotometric measurement of dehydrogenase activities of cells. Disulfonated tetrazolium salt IPB, that produces a highly water-soluble formazan dye that proved to be extremely useful as a cell-viability indicator. IPB is reduced by reduced nicotinamide adenine dinucleotide […]

Cell permeable resorufin derivative used as a fluorogenic indicator for cell viability. Resorufin was selected as the fluorophore because it fluoresces at a longer wavelength and is amenable to modification at the hydroxyl group which is essential for its fluorescence. Incubation with esterase at pH 8.0 results in a 80-90 nm shift of emission max. […]
