Beschreibung
Zusammenfassung:	The present invention relates to a process for purifying Factor IX from an impure protein fraction containing Factor IX. The purification process comprises the steps of adding a solvent and a detergent to an impure protein fraction and incubating the solvent/detergent protein solution to inactivate any viral contaminants. Factor IX is purified from the solvent/detergent protein solution by chromatography on a sulfated polysaccharide resin without first removing the solvent and detergent prior to the purification on the sulfated polysaccharide resin. The Factor IX, purified by the process has a specific activity of at least 85 units/mg.
