von Willebrand factor precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-VWF antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

Von Willebrand factor (VWF) is an adhesive glycoprotein synthesized only by endothelial cells and megakaryocytes, a platelet precursor. It is stored in α-granules in megakaryocytes or Weibel-Palade bodies in endothelial cells. In immature state, it is called as pre-pro-VWF molecule. It consists of D1 and D2 domains which are essential for multimerization. Upon maturation, it develops two other domains. During maturation the signal peptide of pro-VWF is cleaved to form C-terminal dimers in endoplasmic reticulum. The dimers are subjected to further modifications such as carbohydrate processing, sulfation and amino-terminal multimerization. The mature VWF plays major role in hemostasis. It helps in attaching platelets through the glycoprotein Ib receptor to subendothelial tissue at the site of vascular injury and also acts as a carrier protein for protecting coagulation factor VIII from proteolytic degradation by plasma enzymes. Deficiency or any alteration in VWF results in von Willebrand disease, a common hereditary bleeding disorder.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
