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.

Application

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

This protocol describes the use of the 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) salt to evaluate the cell redox potential of rhizobia cells. The production of brightly colored and insoluble 1,3,5-Triphenyltetrazolium formazan arising from TTC reduction is irreversible and can be easily quantified
