Ultrapurification process for factor VIII

摘要

A process for purifying Factor VIII:C comprising contacting an immobilized antibody specifically binding a Factor VIII:C with Factor VIII: C, desorbing Factor VIII:C from the antibody which had adsorbed it, eluting Factor VIII:C from the presence of the antibody, passing the eluted Factor VIII:C through an affinity region capable of binding the Factor VIII:C, binding the Factor VIII:C in the affinity region and passing contaminants through said region, and eluting the purified Factor VIII:C.
