| Description | AURAMINE (C.I. 41000) FOR MICROSCOPY |
| Overview | Auramine O (C.I. 41000) is a dry dye for fluorescence and can be used for the staining of Mycobacteria in smears and sections of human origin. The mechanism is a non-specific binding of fluorescence dye on a substrate, similar to the classical Ziehl-Neelsen method, although the heating of the Auramine O color solution can be avoided. The dye is a CE certified IVD product and has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining. |
