Giemsa's staining is one of the standard procedures in histology, hematology, cytology and bacteriology. The Giemsa's azur-eosin-methylene blue dye is a dry dye that is used for the preparation of a staining solution. This solution can be used for the staining of blood and bone marrow smears, paraffin sections, spirochaets and clinical-cytological specimens of human origin. The stain demonstrates various cells with their morphological features better than e.g. with H&E stain in histology and it can also be used to detect Helicobacter pylori in gastric tissue biopsies. Alternatively, for some applications, among others, May-Grünwald's eosin-methylene blue can be used as a substitute for Giemsa's solution. The dye is an IVD product and CE registered, thus follows extremely high quality standards.
