In order to produce a more well defined interface between adjacent cell layers in a centrifuged sample of anticoagulated whole blood, a material which will bond one group of cells together is added to the blood sample prior to centrifugation. The bonding material must produce a high strength bond between one group of cells, but not effect the other cell types. The material is added prior to centrifugation of the blood sample.
