The Uses of Triphenylformazan

1,3,5-Triphenyltetrazolium formazan has been used:

for the quantification of 2,3,5-triphenyltetrazolium chloride (TTC) reduction activity in bacterial cells
as a standard to study the optical density of formazan produced by TTC-treated milled seeds
to stain heart tissue for infarct size assessment or undergo perfusion fixation to allow morphometric studies in addition to histology and immunohistochemistry

General Description

1,3,5-Triphenyltetrazolium formazan is an insoluble compound produced upon the reduction of 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) salt, which is an indicator of cell redox potential. This reaction is irreversible. TTC formazan is brightly colored and can be quantified using a spectrophotometer.
