Reaction Scheme
Product Description
1-Methoxy PMS is easily dissolved by water and alcohol. Its redox potential is +63 mV. Though phenazinium methylsulfate (PMS) is commonly used as an electron carrier for NADH-tetrazolium, the stability of PMS is very poor. However, 1-Methoxy PMS solution can be stored at room temperature for over 3 months without protection from light. An electron of NAD(P)H is transfered by 1-Methoxy PMS to tetrazolium salt (Reaction Scheme). Therefore, it is a useful reagent for NAD(P)H-tetrazolium-based assay systems.
