(消光系数)Extinction coefficient: EM for oxidized phenazine methosulfate (PMS) at maximum wavelength 387 nm is 26,300 (pH 2-8). The difference in molar extinction
coefficients between oxidized and reduced PMS is 25,000.
Melting Point: 158-160 °C
用途:PMS is an electron acceptor and carrier in enzyme systems. The oxidized form is yellow and the reduced form is colorless. 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. PMS is reduced by flavoproteins such as succinic dehydrogenase. PMS is reduced non-enzymatically by NADH and NADPH. PMS is also reduced by dithionite, sodium borohydride, ascorbic acid, reduced ubiquinones, and reduced vitamin K. PMS reacts with sulfhydryl groups including those of enzymes. Usage of PMS for detection of specific dehydrogenases has been reported.
