General description

Azure II (C.I. 52010/ 52015), is a dry dye for the preparation of a color staining solution used for the staining of blood and bone marrow smears of human origin. The present dye Azure II (C.I.52010/52015) - for microscopy is a defined dye mixture of azure I and methylene blue (1+1), for use in hematological stainings by addition of eosin Y. 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. 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. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
