VWF Antibody from BIOLEGEND

Von Willebrand factor (VWF) plays a crucial role in blood clotting by assisting platelets in forming clots at the site of blood vessel injury. Acting as a bridge between platelets and the damaged blood vessel walls, VWF facilitates platelet adhesion and aggregation, which are essential steps in the clotting process. Moreover, VWF also stabilizes factor VIII, a key protein in the blood clotting cascade, preventing its degradation and enhancing its availability for clot formation. Mutations or deficiencies in VWF results in defects in platelet adhesion and potentially bleeding disorders such as thrombotic thrombocytopenic purpura, Heyde’s syndrome, and von Willebrand disease. A critical region of VWF is the A2 domain. Contained in this domain is the cleavage site for the ADAMTS13 protease which inactivates VWF.
