The May-Grünwald Eosin Methylene Blue by Dinâmica, available at LojaLab, is a solid Romanowsky-type dye mixture based on methylene blue and yellowish eosin, supplied for preparation of staining solutions for hematology smears. In May-Grünwald or May-Grünwald-Giemsa procedures, the basic and acidic dye components create contrast among nuclei, cytoplasm, erythrocytes and cellular granules. Solvent, buffer, pH, staining time and sequence must therefore follow the laboratory method.
