Abstract Share this page

The fractionation of sub-populations of peripheral blood mononuclear cells has become an essential routine procedure and some of the main fractionation methods used today are immunomagnetic separations. We describe a less expensive method for the separation of subpopulations of mononuclear cells using density perturbation, which uses the binding of antibody-coated dense polystyrene beads to increase the density of specific sub-populations of cells. By incubating a total mononuclear fraction from human peripheral blood together with antibody-coated beads, in a commercially-available lymphocyte separation medium (Nycoprep 1.077), a depletion of 94.9 ± 1.68% of the T cells could be obtained by this procedure; a depletion of 69.7 ± 1.78% of the B cells was also achieved. These results indicate the potential for the separation of different sub-populations of peripheral blood mononuclear cells on the basis of the immunological identity of the surface of cells using density perturbation methods involving antibody-coated dense polystyrene beads.
