Superficial Accumulation of Plasminogen During Plasma Clot Lysis

We conclude that the generation of potent surface-associated plasminogen-binding sites during thrombolysis results in a strikingly high plasminogen concentration at the dynamically changing surface of a lysing clot. The necessity of a continuous plasminogen supply from the plasma supports the use of fibrin-specific and plasminogen-sparing agents for thrombolytic therapy.
