PROLONGED PRESERVATION OF BLOOD PLATELETS

摘要

This invention provides a method for prolonging the preservation of human blood platelets at reduced temperatures. The method uses an inhibitor system that enables blood platelets to maintain their discoid shape and retain their functional integrity during storage. This is accomplished by interrupting normal platelet function during storage, so as to help keep platelets from activating and losing their shape. Before using the platelets in a transfusion, they are returned to their normal functional level by washing the inhibitor system away from the platelets.
