2,3,5-Triphenyltetrazolium chloride (TTC; Tetrazolium chloride) S210 Proteinase K is stable inTetrazolium red is used to visualize dehydrogenase enzyme activity. Initially, the tetrazolium solution is colorless but changes to red when it comes into contact with hydrogen. Tetrazolium red is used in a biochemical viability test for seeds. The test relies on dehydrogenase enzymes to release hydrogen ions, which subsequently reduce the colorless tetrazolium salt solution to a red compound called formazan. Living cells turn red while dead cells
