1-Methoxy PMS, electron mediator (5163-100mg)

1-Methoxy PMS (1-methoxy-5-methylphenazinium methyl sulfate) is a stable, water-soluble electron-transfer mediator critical for biochemical assays involving NAD(P)H-dependent dehydrogenases. It facilitates electron shuttling between intracellular NAD(P)H and extracellular tetrazolium dyes (e.g., WST-8), allowing for the real-time monitoring of cellular metabolic activity without cytotoxicity. Its enhanced stability over traditional phenazine methosulfate (PMS) makes it ideal for long-term experiments.
