Plasminogen activator capable of being activated by thrombin

摘要

A plasminogen activator (t-PA) is (a) modified in such a way that it can be split by thrombin and thus turned into its two-chain form; (b) modified in such a way that its zymogenity is at least 1.2 higher than that of t-PA; and (c) its fibrin binding power is so reduced that more than 50 % of the plasminogen activator can enter a blood clot. This plasminogen activator has an improved fibrin-specificity and less side effects.
