Reduction of the antigenicity of factor VIII toward complex inhibitory antibody plasmas using multiply-substituted hybrid human/porcine factor VIII molecules
15 Jan 2000
Abstract excerpt
Factor VIII (fVIII) circulates as a heavy chain/light chain (A1-A2-B/ap-A3-C1-C2) heterodimer. The 41-residue light chain activation peptide, ap, is cleaved from fVIII during proteolytic activation by thrombin or factor Xa. We constructed 7 active recombinant hybrid B-domainless human/porcine fVIII molecules that contained combinations of porcine sequence replacements within the A2, ap-A3, and C2 domains. The...
