    Product Information

    Product Usage Information

    This product is the carrier free version of product #14960. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

    This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

    BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

    Formulation

    Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

    For standard formulation of this product see product #14960

    Storage

    Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

    Specificity / Sensitivity

    EphB4 (D1C7N) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total EphB4 protein.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human EphB4 protein.

    Background

    The Eph receptors are the largest known family of receptor tyrosine kinases (RTKs). They can be divided into two groups based on sequence similarity and on their preference for a subset of ligands: EphA receptors bind to a glycosylphosphatidylinositol-anchored ephrin A ligand; EphB receptors bind to ephrin B proteins that have a transmembrane and cytoplasmic domain (1,2). Research studies have shown that Eph receptors and ligands may be involved in many diseases including cancer (3). Both ephrin A and B ligands have dual functions. As RTK ligands, ephrins stimulate the kinase activity of Eph receptors and activate signaling pathways in receptor-expressing cells. The ephrin extracellular domain is sufficient for this function as long as it is clustered (4). The second function of ephrins has been described as "reverse signaling", whereby the cytoplasmic domain becomes tyrosine phosphorylated, allowing interactions with other proteins that may activate signaling pathways in the ligand-expressing cells (5). Various stimuli can induce tyrosine phosphorylation of ephrin B, including binding to EphB receptors, activation of Src kinase, and stimulation by PDGF and FGF (6). Tyr324 and Tyr327 have been identified as major phosphorylation sites of ephrin B1 in vivo (7).

    The ephrin receptor B4 (EphB4) is normally expressed on venous endothelial cells, while arterial endothelial cells express its ligand, EphrinB2. Together, EphB4 and EphrinB2 play an important roll in vasculature development and maintenance (8). Research studies show that various cancers, including breast, colorectal, esophageal, and pancreatic cancers, express EphB4 (9-12). However, as EphB4 has been shown to have both tumor suppressive and promoting properties, its role in tumorigenesis and tumor progression remains uncertain (13).
