Description

Description: The monoclonal antibody 25H11 recognizes mouse Ephrin B1, a 47 kDa membrane protein. Ephrin B1 belongs to a family of ephrins composed of type A (linked to the cell membrane through a glycosylphosphatidyl inositol group) or type B (transmembrane) proteins. The type B ephrins consist of 3 members (B1, B2, and B3) each of which contains a cytoplasmic domain containing tyrosine residues that can be phosphorylated. Ephrin B and ephrin B receptors (Eph B) can interact to potentiate bidirectional downstream signaling between cells expressing either or both the ligand and receptor. Ephrins have been shown to play a role in neural crest cell development through both neurogenesis and neural migration, as well as development of kidney and heart cyto-architecture. Overexpression of type B ephrins in cancer cells is associated with increased vascularity and highly invasive tumors. Applications Reported: This 25H11 antibody has been reported for use in immunohistochemical staining of frozen tissue sections and immunoprecipitation. Applications Tested: This 25H11 antibody has been tested immunohistochemistry on frozen mouse kidney tissue sections at less than or equal to 10 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

Cell surface transmembrane ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Binds to receptor tyrosine kinase including EPHA4, EPHA3 and EPHB4. Together with EPHB4 plays a central role in heart morphogenesis and angiogenesis through regulation of cell adhesion and cell migration. EPHB4-mediated forward signaling controls cellular repulsion and segregation from EFNB2-expressing cells. May play a role in constraining the orientation of longitudinally projecting axons.
