Description and Uses

Phenazine is a free radical generator. It has been used as an electron transfer reactant in cell viability assays. Phenazine (10 μM) induces ssDNA break formation in the presence of the reducing agent NADPH in a cell-free plasmid cleavage assay when used at a concentration of 10 μM. It induces oxidative DNA damage in an alkaline comet assay and apoptosis in A375 melanoma cells when used at a concentration of 10 μM. Phenazine (20 nM) oxidizes cysteine-containing proteins in HepG2 cells.

Phenazine Methosulfate is used in tyrosine transaminase test and for enzymic determination of ethanol in blood by the colorimetric micromethod. Used with ascorbic acid to determine nitric oxide reductase activity. Since the reduced PMS is easily oxidized by oxygen, it is used in assays as an electron carrier between enzymes and oxygen, cytochrome c, indophenols, or tetrazolium salts. The reduced PMS is used as an electron donor to reduce cytochrome c or in photosynthetic experiments. Usage of PMS for detection of specific dehydrogenases has been reported.
