Rapid separation of large numbers of human peripheral blood mononuclear cells into fractions enriched for B lymphocytes, T lymphocytes, or monocytes was accomplished by counterflow centrifugal elutriation (CCE). The first fraction contained 98% of the platelets. Ten additional fractions containing subpopulations of mononuclear cells were collected by sequential increases in the flow rate while maintaining a constant centrifuge speed. Analysis of the fractions using monoclonal antibodies revealed that fraction 2, which was free of esterase-positive monocytes, was highly enriched for B cells. T lymphocytes (OKT3+) were the predominant cell type found in fraction 4. No enrichment for T-lymphocyte-helper (OKT4+) or -suppressor (OKT8+) subpopulations was observed in the lymphocyte containing fractions. Three fractions (7-9), highly enriched for esterase-positive cells, were predominantly OKM1+ monocytes with no evidence of selective separation of monocyte subpopulations. Thus, cell fractions enriched for B cells, T cells, and monocytes could be obtained, by utilizing CCE, in large enough quantities to enable analysis of their functional properties. Of particular interest was the ability to separate small, resting B lymphocytes from monocytes.
