一般描述

Azure II Eosinate is the eosinate of the dye Azure II which is a mixture of the dyes methylene blue and azure B in equal proportions. This compound is a key ingredient in Giemsa stain, which is widely utilized for staining blood elements and facilitating the visualization of cellular components under a microscope.

应用

Azure II Eosinate is used for human-medical cell staining and serves the purpose of the investigation of sample material of human origin (by fixing, embedding where necessary, staining, counterstaining, mounting) in hematological and clinico-cytological specimen materials, for example smears of whole blood and bone marrow.

特点和优势

Chief ingredient of Giemsa Stain.

原理

The staining of the nuclei is due of the molecular interaction of the Eosin Y dye and a complex of Azure B with DNA. Both dyes assemble to an Eosin Y- Azure B-DNA complex and the intensity of the resulting stain depends on the content of Azure B and the ratio of Azure 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.
