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

Supplier: SIGMA ALDRICH MICROSCOPY

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.

Acridine orange base ≥75% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Acridine Orange base (3,6-Bis(dimethylamino)acridine) is a cell-permeable fluorescent dye that binds to nucleic acids. It emits green fluorescence when bound to dsDNA and red fluorescence when bound to ssDNA or RNA. It is also known to be a positive solvatochromic dye. Acridine orange has also been used as a lysosomal dye. It is widely used to detect the presence of homeopathic potencies.
