Electrophoretic mobility distributions distinguish hairy cells from other mononuclear blood cells and provide evidence for the heterogeneity of normal monocytes.

Abstract

The electrophoretic mobility distributions of hairy cells, normal monocytes. CLL, and normal lymphocytes isolated from blood were determined by electrophoretic light scattering. Values obtained for hairy cells, 1.52 X 10(-4) cm2/V . sec, were indistinguishable from that of normal monocytes. The mobility of CLL lymphocytes was similar to that of normal B cells. After exposure to neuraminidase, hairy cells revealed a homogeneous distribution with a reduced mobility of 0.55 X 10(-4) cm2/V . sec, while normal monocytes showed a heterogeneous distribution of electrophoretic mobilities suggestive of subpopulations. The electrokinetic behavior of hairy cells thus differs from that or normal and CLL lymphocytes before, and from that of monocytes after, treatment with neuraminidase. The hairy cell therefore possesses a distinct pattern of surface charge properties that clearly distinguish it from the circulating B cells, T cells, or monocytes.
