This invention provides a process for preparing a fibrin-adsorable protein-urokinase complex characterized by reacting a protein adsorbable by fibrin with urokinase in the presence of a protein coupling reagent represented by the formula ##STR1## wherein R is phenylene or cycloalkylene, A is lower alkylene, B is lower alkylene which may optionally be substituted by lower alkylthio or phenyl-lower alkylthio, and l, m and n are each 0 or 1 provided that l, m and n are not 0 at the same time. The complex is useful as a thrombolytic agent.
