title: Tissue-type plasminogen activator: characteristics, applications and production technology.
abstract: Plasminogen activators have immense clinical significance as thrombolytic agents for management of stroke and myocardial infarction. Tissue-type plasminogen activator (tPA) is generally preferred as being effective and safer than either urokinase or streptokinase type activators. Large-scale production of tPA became possible through groundbreaking developments in cell lines and bioprocess technology. Nevertheless, at thousands of dollars per treatment, tPA remains expensive. Enhancing cellular productivity and downstream product recovery through new approaches continue to be major challenges as discussed in this review. Recent clinical experience suggests the need for yet better fibrinolytic agents and attempts are underway to modify the tPA molecule to second generation products. Emerging trends in this field are outlined.
