A novel triple-kringle plasminogen activator protein, PKlAFElX, has been produced which is a genetic chimera between the fibrin binding kringle 1 domain of plasminogen and the two kringles and serine protease domains of naturally occurring wild-type tissue plasminogen activator (wt t-PA). This chimera also contains a modification to prevent high mannose(More)
Human tissue-type plasminogen activator (t-PA) is a glycoprotein used currently in thrombolytic therapy. Because of its rapid half-life (T1/2) of approximately five minutes, intravenous (IV) infusion of large doses (approximately 100 mg) are required in patients treated for myocardial infarction. To identify the determinant(s) on t-PA responsible for such(More)
Human tissue-type plasminogen activator (t-PA) is a glycoprotein used currently in thrombolytic therapy for patients with acute myocardial infarction. Due to its rapid rate of clearance from the circulation, continuous intravenous administration of approximately 100 mg over 3 h is recommended. We have previously characterized novel thrombolytic variant(More)

Recombinant variants of tissue plasminogen activator (t-PA) containing either substitutions or deletions of amino acids within the fibronectin finger-like domain (residues 6-50) were found to exhibit widely varying in vivo clearance profiles in rats and fibrinolytic activity in 125I-fibrin clot lysis assays. Clearance was not significantly affected by(More)
