But before it actually becomes active, it must be activated by tissue tie plasminogen activated TPA. And once TPA activates plasmidogen, the plasma then locates that blood clot that consists of those fibrin molecules. And it cleaves, it breaks the peptide bond in those fibrin molecules. And then the fibrin molecules basically dissociate from that blood vessel wall and they travel to the liver cell and the liver cells essentially digest and recycle those blood clots. So Plasmid is a serum protease which is responsible for actually breaking down and digesting those blood clots. And that ultimately prevents the process of thrombosis from actually taking place.
