  5. Auramine O Stain Kit

    Auramine O Stain Kit

    Starting at: $180.00

    Acid-fast mycobacteria resist decolorization by acid-alcohol after primary staining owing to the high lipid (mycolic acid) content in their cell walls. The identification of mycobacteria with auramine O is due to the affinity of the mycolic acid in the cell walls for the fluorochromes. The dye will bind to the mycobacteria, which appear as bright yellow luminous rods against a dark background. The potassium permanganate helps prevent non-specific fluorescence.
