1-Methoxy-5-methylphenazinium methyl sulphate ≥95%, Sigma-Aldrich®

Leverantör: SIGMA ALDRICH MICROSCOPY

Beskrivning: 1-Methoxy-5-methylphenazinium methyl sulfate (MPMS) is a photochemically stable electron-transport mediator between NAD(P)H and tetrazolium dyes. The reduced form of MPMS converts tetrazolium salt to purple precipitate formazan. It is a very stable and non-enzymic electron carrier that mediates electron transfer by dehydrogenases in vitro to various electron acceptors such as tetrazolium dyes or the electrode of an enzymic electric cell.
