Mononuclear cells (lymphocytes and monocytes) can be isolated from other blood cell elements on the basis of their lower density. There are three variations of the basic method: (1) sedimentation on to a density barrier using diatrizoate (plus a polysaccharide) or Nycodenz or iodixanol; (2) flotation after raising the density of the plasma by mixing blood with Nycodenz or iodixanol; (3) flotation through an iodixanol density barrier.
