2,3,5-Triphenyltetrazolium chloride by Molecular Depot is a 2,3,5-triphenyltetrazolium chloride, also called tetrazolium red, used to measure dehydrogenase activity. The colourless salt is reduced by cellular dehydrogenases to an insoluble red formazan, so tissue or cells that are metabolically active stain red and dead material does not. It is used to assess tissue viability and infarct size in histology, to test seed viability and in dehydrogenase and respiration assays. Each unit contains 5 g. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
