描述

一般說明

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 has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
