An ultrapurification process for factor VIII:C.

摘要

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