VARIANTS OF TISSUE PLASMINOGEN ACTIVATOR WITH IMPROVED THERAPEUTIC EFFECT

摘要

The invention concerns tissue plasminogen activator (t-PA) variants which are glycosylated at any of positions 103-105, and are devoid of functional carbohydrate structure at position 117 of wild-type human t-PA amino acid sequence. The variants have extended circulatory half-life and substantially retained fibrin binding, or improved in vivo fibrinolytic potency, as compared to wild-type human t-PA. IMAGE
