    同义词 Tetraethylrhodamine, Brilliant pink B
    描述 RHODAMINE B (C.I. 45170) FOR MICROSCOPY
    概述 Rhodamine B (C.I. 45170) is a dry dye for fluorescence Tb 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.
