Concentration of plasminogen and antiplasmin in plasma and serum

Abstract

The concentrations of plasminogen and fast-acting antiplasmin were measured in 65 normal plasmas and matched sera. Concentrations were decreased in serum by 38 % for plasminogen and 32% for fast-acting antiplasmin. The decrease in plasminogen level was due to both adsorption of plasminogen to fibrin and reaction with antiplasmin.
