WebNov 13, 2024 · Plasmin is generated from the inactive zymogen, plasminogen by either tissue plasminogen activator (tPA) or urokinase plasminogen activator (uPA). As both tPA and plasminogen have high affinity for fibrin, fibrin acts as a co-factor for tPA-mediated plasmin generation through co-localization. WebProteins and Reagents—Active tPA (85% single-chain, 15% two-chain) and EI-tPA, which is mutated at two amino acids (S478A and R275E) and thus inactive and non-cleavable were purchased from Molecular Innovations (Novi, MI).
