Von Willebrand Factor is a blood glycoprotein involved in hemostasis. The VWF gene encodes a large multimeric glycoprotein that plays a central role in the blood coagulation system, serving both as a major mediator of platelet-vessel wall interaction and platelet adhesion, and as a carrier for coagulation factor VIII. vWF released from endothelial cell Weibel-Palade bodies bound particularly avidly to the extracellular matrix. Deficiency or dysfunction (von Willebrand disease) leads to a bleeding tendency, which is most apparent in tissues having high blood flow shear in narrow vessels.

Variations in secondary/substrate sensitivities and test protocols may require the von Willebrand Factor antibody to be titrated for optimal performance.

Mouse partial recombinant protein (AA 1304-1452) was used as the immunogen for this von Willebrand Factor antibody.

The von Willebrand Factor antibody can be stored at 4oC to -20oC.After reconstitution, aliquot and store at -20oC.Avoid repeated freeze/thaws.
