Cat. No. : VWF-126H
Description : Factor VIII related antigen or von Willebrand factor is a multimeric glycoprotein. It has functional binding domains to platelet glycoprotein Ib, glycoprotein IIb/IIIa, collagen and heparin. von Willebrand factor is synthesized by endothelial cells and stored in the Weibel-Palade granules. It mediates platelet adhesion to injured vessel walls and serves as a carrier and stabilizer for coagulation factor VIII. von Willebrand factor is one of the most useful markers to identify endothelial (or megakaryocytic) lineage of neoplasms. As not all endothelial cells synthesize / store) this molecule, about 30% of tumors of vascular origin fail to stain for factor VIII related antigen, regardless of whether they are benign or malignant. Staining for factor VIII related antigen has also been used to measure angiogenesis, an indicator of tumor recurrence.

Ask a question
How can treatment be used to change the level or function of the VWF protein? 09/15/2022

There is currently no treatment that directly targets the VWF protein. However, some medications can improve the patient's clotting status and reduce the risk of bleeding. For example, the use of recombinant human coagulation factor VIII. can replace the deficient factor VIII and improve coagulation function. In addition, the use of antifibrinolytic drugs can inhibit the degradation of fibrin and maintain the stability of the coagulation process.

What is the relationship between VWF protein and coagulation factor VIII? 04/28/2022

VWF protein is closely related to coagulation factor VIII. Coagulation factor VIII. is a serine protease that plays a key role in the coagulation process. VWF protein can act as a cofactor for coagulation factor VIII., accelerating the coagulation process. In addition, VWF protein can also inhibit the activity of plasminogen activators, thereby inhibiting the degradation of fibrin and maintaining the stability of the coagulation process.

How does VWF play a role in hemostasis? 10/24/2020

In the process of hemostasis, the role of VWF protein is mainly to promote platelet adhesion and aggregation. When platelets bind to VWF protein, morphological changes occur and the phospholipid surface is exposed, which interacts with other platelets or endothelial cells to form platelet thrombosis and play a hemostatic role.

Is VWF protein related to other coagulation factors? 04/21/2020

There is a complex interaction between VWF protein and other coagulation factors. For example, VWF proteins can bind to glycoprotein II.b/III.a receptors on the surface of platelets, promoting platelet adhesion and aggregation.

What is the association between genetic variation in VWF protein and disease? 03/29/2020

Genetic variations in the VWF protein can lead to coagulation disorders such as von Willebrand disease (VWD). Some variants can cause VWF protein deficiency or dysfunction, which can affect the ability of platelets to adhere and aggregate, increasing the risk of bleeding. Understanding these variants can help diagnose and classify different subtypes of VWD.

What is the function of VWF protein in blood? 02/10/2020

The main function of VWF protein in blood is to promote platelet adhesion and aggregation, thereby participating in the process of hemostasis and coagulation. In addition, VWF protein can also act as a regulator of endothelial cells and participate in the repair and remodeling of blood vessel walls.
