Conjugates of factor IX and a biocompatible polymer

摘要

The invention relates to a conjugate of factor VIII and a biocompatible polymer, said conjugate obtainable by a process comprising: (a) immobilizing factor VIII by interaction with a group-specific adsorbent carrying anionic-exchange ligands; (b) activating a biocompatible polymer; (c) conjugating the activated biocompatible polymer to external sites of the immobilized factor VIII; and (d) eluting the conjugate from the adsorbent.
