von Willebrand Factor (Factor VIII-related antigen) from human plasma.

General description

Human von Willebrand factor (factor VIII R:Ag) is a 270 kDa multimeric plasma gylcoprotein. It mediates platelet adhesion to injured vessel walls and serves as a carrier and stabilizer for coagulation factor VIII. The von Willebrand factor has functional binding domains to platelet glycoprotein Ib, glycoprotein IIb/IIIa, collagen and heparin. The factor is synthesized by endothelial cells and is also present in platelets and megakaryocytes.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide


The antibody specifically reacts with the cytoplasm of human endothelial cells from normal and neoplastic blood and from lymphatic vessels. It also reacts with human endocardium, platelets and megakaryocytes. It may be used for immunohistological studies of the vascular structures in frozen tissue preparations and enzymatically pre-digested, formalin, methacarn, Bouin′s or ethanol-fixed and paraffin-embedded tissue sections.

Preparation Note

Whole antiserum is purified to provide an IgG fraction of antiserum.
