von Willebrand Factor (and VIII Free) PRODUCT INQUIRY Multimeric Structure Of Von Willebrand Factor The formation of a 1.8 MDa von Willebrand factor (vWF) multimer with bound factor VIII is illustrated. Each vWF monomer (Mr=260,000) contains a factor VIII near the NH2-terminal end of the molecule. The monomers are joined end-to-end (NH2 to NH2 and COOH to COOH) by disulfide bonds to form large multimers. The mature multimers can bind one factor VIII molecule per monomeric subunit.
