| Description | WRIGHT'S EOSIN METHYLENE BLUE FOR MICROS |
| Overview | The staining method according to Wright is one of the standard techniques in hematological diagnostic procedures. The dry mixture of the Wright's eosin methylene blue dye is used for the self-preparation of the Wright's staining solution. Like Leishman's eosin methylene blue dye and May-Gruenwald's eosin methylene blue dye, it is used for staining of blood and bone marrow smears and clinical cytological specimens of human origin. The typical resulting color of cell nuclei is purple. The dye is an IVD product and CE registered, thus follows extremely high quality standards. |
