Abstract: The invention is directed to methods of purifying a chimeric protein comprising subjecting the chimeric protein to a factor VIII-specific affinity chromatography, and subjecting the chimeric protein to an AEX chromatography; wherein the chimeric protein comprises a factor VIII protein or a fragment thereof. The chimeric protein purified by the present methods shows improved factor VIII activity.
