triphenyltetrazolium
Triphenyltetrazolium, often abbreviated as TTC, is a chemical compound with the molecular formula C19H15N4. It is a colorless, crystalline solid that is soluble in water and organic solvents. TTC is primarily known for its use as a redox indicator. In biological and chemical contexts, it undergoes reduction to form triphenylformazan, a red, water-insoluble compound. This color change is dependent on the presence of reducing agents, such as active enzymes or viable cells.
The application of triphenyltetrazolium as a viability stain is widespread in microbiology and plant physiology. When
Beyond viability staining, triphenyltetrazolium has found use in other analytical applications. It can be employed in
