Protein complexes having factor VIII:C activity and production thereof.

摘要

Recombinant protein complexes having human Factor VIII:C activity are produced in a eukaryotic host cell by expressing a DNA construct encoding said protein complex joined in reading frame with control sequences providing for the expression of said DNA construct in said host cell, wherein said DNA construct comprises a nucleotide sequence that encodes a first polypeptide homologous to the A domain of human Factor VIII:C linked to a second polypeptide homologous to the C domain of human Factor VIII:C by a polypeptide spacer, wherein the polypeptide spacer is other than the full length B domain of human Factor VIII:C and comprises an amino acid sequence homologous to a human Ig heavy chain hinge region.
