Popis: A labeled 77-kDa complex formed when 125I-thrombin was added to platelet suspensions or to the supernatant solution of ionophore-activated platelets. Prostacyclin inhibited complex formation with whole platelets but not with the supernatant solution of ionophore-activated platelets. This is evidence that the complex formed with a factor secreted from activated platelets. Smaller complexes of 70 and 58 kDa formed between labeled thrombin and lysed platelets. The 77-kDa complex was necessary for the formation of a thrombin-thrombospondin complex.
