Descrizione

Descrizione generale

Reagents and materials supplied in the Blood Vessel Staining Kit are sufficient for staining 100 tissue sections and when stored at 2-8ºC is stable up to the expiration date. ECM590 detects vWF and CD31 in human paraffin embedded tissues. In rat or mouse tissues only the vWF antibody is effective in paraffin; the CD31 antibody does not react with rodent CD31.

Background:

Angiogenesis and tumor-associated neovascularization are complex processes by which new blood vessels are formed from pre-existing vasculature. Several studies implicate tumor-associated blood vessel formation as a central part in the process of growth, invasion and metastasis of malignancies (Rak et al., 1995; Jahroudi & Greenberger, 1995; Saphir, 1997).

The most widely used endothelial cell markers for studying angiogenesis/neovascularization are von Willebrand Factor (Factor VIII Related Antigen) and CD31 (PECAM-1). von Willebrand Factor is synthesized by endothelial cells, causing adhesion of platelets to injured vessel walls and functions as a carrier and stabilizer for coagulation of Factor VIII. CHEMICON′s von Willebrand Factor antibody reacts specifically with the endothelial cells of blood vessels and is a useful marker for the identification of endothelial lineage in tumors. It is important to note that not all endothelial cells synthesize von Willebrand factor, therefore a small percentage of these vascular-rich tumors might not stain with this antibody. CD31 or platelet endothelial adhesion molecule (PECAM-1), is a type I integral membrane glycoprotein and a member of the immunoglobulin super family of cell surface receptors. It is strongly expressed by all endothelial cells and weakly by several types of leucocytes (Parums et al., 1990). According to several studies, staining of blood vessels with CD31 antibodies has shown to be suitable for the identification of angiogenesis in several types of malignancies such as lung (Giatromanolaki et al., 1996), breast (Horak et al., 1992) and colorectal cancer (Takebayashi et al., 1996). CHEMICON′s monoclonal antibody to CD31 is very specific for the staining of vascular endothelial cells in normal and cancerous tissue.

CHEMICON′s Blood Vessel Staining Kit is a very sensitive immunohistochemical tool for the detection of vascular endothelial cells, containing both anti-von Willebrand Factor and anti-CD31 primary antibodies and is applicable to a variety of species. This immunoperoxidase kit provides a simple, all-in-one method for the staining of frozen and paraffin-embedded sections in human (both CD31 and VWF) or rat and mouse (VWF only) tissues
