碘硝基四唑紫 146-68-9 Iodonitrotetrazolium chloride（INT）

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.色度法检测各种脱氢酶的电子受体（Electron acceptor）碘硝基四唑紫已用于细胞染色。它已被用作 D-阿拉伯糖醇的酶促测定中的偶联剂。
