| 摘要 |
This invention is directed to the cytology of blood, bone marrow and lymph node cells and the method of differentiating, identifying and enumerating said cells among a plurality of cells of hematopoietic origin. More specifically, the invention is directed to the use of a single cationic sulfur-containing azo dye in solution capable of staining said cells in a fixative. The dye is a water soluble quaternary azo dye identified in the Color Index as Basic Blue 41 capable of staining a plurality of cells including malignant cells of hematopoietic origin wherein the stained cells acquire individual color characteristics permitting the differentiation, identification and enumeration of each stained cell. The stained cells obtained by the process of this invention have individual color characteristics which permit the identification and differentiation by use of various instruments including, for example, an image analyzer, microscope, photomicroscope, and the like.
