Azure B (C.I. 52010) for microscopy
Azure B belongs to the basic coal tar dyes (methylene blue and its derivatives). These dyes are mainly used for staining of blood elements. In watery solution they form special salts with the acid eosin, the eosinates.
Besides eosin and methylene blue Azure B is the main component of Giemsa staining solution (Art. No. T862). The Azure B eosinates in the solution cause the so called “Romanowsky-Giemsa effect”, a polychromatic, pH-dependent staining of chromatin.
