Format
Lyophilized
Reconstitution
Allow the vial and reconstitution buffer to equilibrate to room temperature. Briefly centrifuge or tap down the vial to ensure that all lyophilized powder is collected at the bottom of the vial. For the reconstitution of this product, we recommend adding PBS or sterile water to achieve a final antibody concentration of 1 mg/mL. Allow the vial to reconstitute for 10-15 minutes at room temperature with gentle agitation. Avoid vigorous shaking that can cause foaming and antibody denaturation. Aliquot into volumes based on your experiment and store liquid protein at -20°C or -80°C for long time.
Buffer
Lyophilized from sterile PBS
Preservative
None
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
More Infomation

Target

Full Name
Von Willebrand Factor
Function
Important in the maintenance of hemostasis, it promotes adhesion of platelets to the sites of vascular injury by forming a molecular bridge between sub-endothelial collagen matrix and platelet-surface receptor complex GPIb-IX-V. Also acts as a chaperone for coagulation factor VIII, delivering it to the site of injury, stabilizing its heterodimeric structure and protecting it from premature clearance from plasma.

Involvement in disease
von Willebrand disease 1 (VWD1):
A common hemorrhagic disorder due to defects in von Willebrand factor protein and resulting in impaired platelet aggregation. Von Willebrand disease type 1 is characterized by partial quantitative deficiency of circulating von Willebrand factor, that is otherwise structurally and functionally normal. Clinical manifestations are mucocutaneous bleeding, such as epistaxis and menorrhagia, and prolonged bleeding after surgery or trauma.
von Willebrand disease 2 (VWD2):
A hemorrhagic disorder due to defects in von Willebrand factor protein and resulting in altered platelet aggregation. Von Willebrand disease type 2 is characterized by qualitative deficiency and functional anomalies of von Willebrand factor. It is divided in different subtypes including 2A, 2B, 2M and 2N (Normandy variant). The mutant VWF protein in types 2A, 2B and 2M are defective in their platelet-dependent function, whereas the mutant protein in type 2N is defective in its ability to bind factor VIII. Clinical manifestations are mucocutaneous bleeding, such as epistaxis and menorrhagia, and prolonged bleeding after surgery or trauma.
von Willebrand disease 3 (VWD3):
A severe hemorrhagic disorder due to a total or near total absence of von Willebrand factor in the plasma and cellular compartments, also leading to a profound deficiency of plasmatic factor VIII. Bleeding usually starts in infancy and can include epistaxis, recurrent mucocutaneous bleeding, excessive bleeding after minor trauma, and hemarthroses.
