Based on the previous finding that erythrocytes from patients with chronic myelogenous leukemia stain with the fluorescent dye merocyanine 540, erythrocytes from patients with other myeloproliferative disorders were examined for their ability to bind the membrane probe. As assessed by both fluorescence staining and a quantitative dye removal assay, all samples of erythrocytes from patients with chronic myelogenous leukemia, polycythemia vera, myelofibrosis with myeloid metaplasia and essential thrombocythemia bound more dye than did erythrocytes from normal, healthy individuals. Erythrocytes from three of six patients with acute myelogenous leukemia also showed increased affinity for the dye. In contrast, erythrocytes from three patients with acute lymphocytic leukemia and one with unclassifiable leukemia bound only normal amounts of dye. The procedures described may be useful as a supplemental aid to diagnosis of myeloproliferative disorders or for investigation of hematological diseases where multilineage involvement is suspected.

Merocyanine 540 is a fluorescent dye which stains erythrocytes that have lost their normal membrane phospholipid asymmetry. Because erythrocytes from patients with chronic myelogenous leukemia have been reported to display this abnormal phenotype, peripheral blood erythrocytes from such patients were examined for their ability to stain with the dye. Erythrocytes from all patients with active disease states stained, whereas neither erythrocytes from normal, healthy individuals nor from a patient whose disease symptoms were eliminated by chemotherapy stained. These results suggest that merocyanine 540 may have utility in the clinical evaluation of chronic myelogenous leukemia.
