General description

Wright’;s eosin methylene blue - for microscopy staining dye, is a defined mixture of the dyes C.I. 52015 and C.I. 45380 for hematological staining procedures and is used in conjunction with eosin Y. The Wright’;s eosin methylene blue solution can be used for analysis and diagnostics in the whole blood differentiation. The staining of the nuclei is due of the molecular interaction of the Eosin Y dye and a complex of Azur B with DNA. Both dyes assemble to an Eosin Y - Azur B-DNA complex and the intensity of the resulting stain depends on the content of Azur B and the ratio of Azur B : Eosin Y. Furthermore, the resulting stain can vary depending on the influence of fixation, staining times, pH-value of the solutions or buffer substances.
