Surface Markers on Human B and T Lymphocytes

A procedure to assess the cellular adherence displayed by lymphocytes, at the level of the single cell, is described. Adherence is defined as the capacity of a cell to hind acrylic acid polymer beads. 0.5 μm: in size, under standardized conditions These beads were found to adhere readily to lymphocytes that have a high density of surface immunoglobulin Such cells can be distinguished from other leukocytes with the same binding capacity by the extracellular localization of the beads on these cells Furthermore, adherence, as presently defined, is briefly characterized.
