Descrizione

Descrizione generale

Rhodamine B (C.I. 45170) for microscopy, is a solid dye for fluorescence AFB staining of bacteriological smears and histological tissue 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 Rhodamine B 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. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
