Abstract
There is provided in accordance with the practice of this invention a process for separating Factor VIII complex from an impure protein fraction containing Factor VIII complex. An aqueous solution of the impure protein fraction containing Factor VIII complex is applied to a heparin-coupled chromatographic medium, to bind the Factor VIII complex to the medium. The Factor VIII is then recovered from the heparin-coupled chromatographic medium by elution with an aqueous solution comprising CaCl.sub.2 and histidine. The recovered Factor VIII is further purified by precipitation with a solution comprising glycine and NaCl, and washing the resultant precipitate with a solution comprising histidine, glycine, and NaCl to provide a Factor VIII complex solution with a specific activity of about 70 to about 150 units/mg.
