title: Interaction of platelets with purified macromolecules of the arterial wall.
abstract: A method is described for the study of the interaction between human blood platelets and intercellular matrix macromolecules of connective tissues such as those found in the sub-endothelium. The method is based on the qualitative and quantitative evaluation of the elution pattern of a platelet suspension from a mixed Sepharose 2B-fibrous protein column containing standardized amounts of fibrous proteins such as elastin or structural glycoprotein-microfibrils (SGP-MF). No interaction could be demonstrated with this method between platelets and SGP-MF but there was a very distinct interaction between platelets and elastin fibers. This could be confirmed by direct microscopical demonstration of platelet clusters around elastin fibers in cryostat sections of the affinity column.
