title: The analysis of the variation of the surface proteins of leukemic lymphocytes of B-chronic lymphocytic leukemia patients by high performance liquid chromatography.
abstract: Surface phenotypes of leukemic lymphocytes are analyzed by high performance liquid chromatography of the vectorially iodinated surface proteins and the variation of the phenotypes of B-chronic lymphocytic leukemia (B-CLL) lymphocytes from different individuals is studied. A number of surface molecules show a coordinated variation between patients in their level of expression. Some of these molecules belong to recognized clusters of differentiation, e.g., CD45 and CD21 and their variation can be confirmed by flow cytometry. But the HPLC also reveals other components that have not been assigned to known clusters, e.g., a component of Mr of around 300 kD. Two types of B CLL lymphocytes can be recognized by this set of molecules and the patients ranked according to the level of expression of these markers on their leukemic cells. The effects of TPA treatment on expression suggests that these molecules represent a maturational sequence and that the leukemias are derived from progressive stages along this process.
