Process for preparing a polysaccharide derivative of plasmin

THE PROCESS OF THE INVENTION IS TO MAKE REACT WITH plasmin DIALDEHYDODEXTRANE OF MOLECULAR WEIGHT OF A 20000 110000 AT A PH 8.0 A 9.5 A TEMPERATURE AND 5 TO 30C, REDUCING pOLYSACCHARIDE DERIVATIVE OF plasmin BY boronitride SODIUM AND THEN THE SEPARATION. THE plasmin OF pOLYSACCHARIDE DERIVATIVE OBTAINED THIS ACTIVITY THROMBOLYTIC PROLONGED AND SEEK MEDICAL APPLICATIONS.
