Anti-EFNB2 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.

Ephrin-B2 (EFNB2) regulates sprouting and proliferation of endothelial cells in the endothelium of the developing vasculature. This is in turn, linked with vascular endothelial growth factor (VEGF) receptor endocytosis and signaling. It is crucial in supporting pericytes and vascular smooth muscle cells (VSMCs). It also functions as the regulator of the distribution, internalization and signaling of platelet-derived growth factor receptor β (PDGFRβ) in VSMCs. In castration resistant prostate cancer (CRPC), the expression of this gene is directly suppressed by miR-582-5p. Therefore, it might function as a tumor suppressor functioning through EphB4, in cancer cells expressing EphB4. This protein is responsible for the induction of neuronal differentiation of neural stem cells (NSCs), when presented by neighbouring astrocytes. EFNB2 participates in the development of the cardiovascular system, postnatal angiogenesis, and cardiac remodeling. It serves as a modulator in transforming growth factor-ß (TGF-ß)-mediated organ fibrosis.

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.

EFNB2 (ephrin-B2) is a member of the B-class ephrins, which function as ligands for EphB RTKs (receptor tyrosine kinase). It is a transmembrane protein. It is a cell surface signaling glycoprotein, which has a ubiquitous expression pattern. EFNB2 is expressed in mesenchymal cells, with the highest expression in fibroblast. EFNB2 gene is located on human chromosome 13q33.3.
