(TTC, Tetrazolium Red, 2,3,5-Triphenyl-2H-tetrazolium chloride, Tetrazoliumchloride)

Triphenyltetrazolium chloride, abbreviated TTC, is used in biochemistry to measure the activity of dehydrogenases. In vital staining living cells are detected through the reduction of the colourless, water-soluble tetrazolium dye to a deep red, water-insoluble formazan via the dehydrogenases of the respiratory chain. Furthermore, TTC can be used in microbiology to distinguish between coliform and noncoliform bacteria, to measure the bacterial content of liquids in food analysis and to determine seed vitality.
