説明Iodonitrotetrazolium (INT) (chloride) is a monotetrazolium salt used as an indicator dye. It is reduced to an insoluble formazan that is used as a vital dye or indicator of cellular redox activity. Reduction commonly results from the activity of dehydrogenases, although non-enzymatic electron transfer reactions can occur in the presence of an intermediate electron acceptor. INT is commonly used to measure the respiratory activity of microorganisms in a variety of contexts.
使用Iodonitrotetrazolium chloride has been used for the staining of cells. It has been used as a coupling agent in the enzymatic assay of D-arabinitol.
純化方法Recrystallise the chloride from H2O, aqueous EtOH or EtOH/Et2O. Alternatively, dissolve it in the minimum volume of EtOH and add Et2O; or dissolve it in hot H2O (charcoal), filter and precipitate it by adding conc HCl. Filter the solid off and dry it at 100o. Its solubility in H2O at 25o is 0.5%, and in hot MeOH/H2O (1:1) it is 5%. [Fox & Atkinson J Am Chem Soc 72 3629 1950, Beilstein 26 III/IV 1776.]
