产品介绍 | Iodonitrotetrazolium chloride is an electron acceptor used in various colorimetric assays. The chemical has been mainly documented for its measurement of dehydrogenase activity. In the assay to measure SDH (succinate dehydrogenase) activity, Iodonitrotetrazolium chloride was used as an oxidizing agent being reduced by succinate dehydrogenase. Upon reduction the compound forms a formazan dye measured at 500 nm. Iodonitrotetrazolium chloride has also been used to study the electron transport activity in soils, sediments, and pure enzyme cultures as well as nucleotide diphosphate kinase activity. |
