摘要: Recombinant tissue-type plasmogen activator (rt-PA) was produced in Escherichia coli cells order to obtain an unglycosylated rt-PA (BM 06.021) with increased thrombolytic potency due altered pharmacokinetic properties. The pharmacokinetics were studied rabbits upon intravenous infusion of 200 kU/kg over 30 min. dose-response effects evaluated a rabbit model 125I-labeled venous thrombi 4 h. after bolus injection BM 06.021 investigated canine coronary artery thrombosis. All studies performed comparing glycosylated (alteplase).
