Electrophoretic distributions of human peripheral blood mononuclear white cells from normal subjects and from patients with acute lymphocytic leukemia

Abstract

The electrophoretic mobilities of mononuclear white cells from the peripheral blood of normal subjects and leukemic patients were measured. Analysis of both fresh and cryopreserved samples of each type showed that cryopreservation had no distinguishable effect on the electrophoretic distribution of either normal or leukemic cells. Mode mobilities (mobilities at which maximum intensities are observed) of cells from nine leukemic patients were 7-28% below the average mode mobility of normal cells. The standard deviation of the electrophoretic mobilities of normal cells was 2%. Normal cells had an asymmetric, often bimodal, electrophoretic distribution; leukemic cells consistently had a single symmetric distribution.
