ABSTRACT:
Cell separation compositions and associated methods effective for separating cells from various biological specimens such as blood are disclosed. The biological specimens are contacted with the cell separation compositions and centrifuged. The cells are separated based upon their buoyant density in the cell separation composition. The cell separation composition contains colloidal silica particles covalently linked to an organosilane having a non-ionic, hydrophilic group.
