Product Type Specific: EphB2 protein kinase pan-specific antibody
Antibody Code: NK267-2
Antibody Target Type: Pan-specific
Protein UniProt: P29323
Protein SigNET: EphB2
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human EphB2 sequence peptide Cat. No.: PE-01BCV85
Antibody Immunogen Sequence: REIQGIFFKEDSHKESNDC
Antibody Immunogen Description: Corresponds to amino acid residues R1033 to C1051; Near C-terminus.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.
Antibody Concentration: 1 mg/ml
Storage Buffer: Phosphate buffered saline pH 7.4, 0.05% Thimerasol

Scientific Background: EphB2 is a receptor protein-tyrosine kinase of the TK group and Eph family. It is activated by binding ephrin-B1, B2, or B3, followed by receptor dimerization. It features an extracellular region for ligand binding, a single transmembrane domain, and a cytoplasmic tyrosine kinase domain. Eph and Eph receptors are associated with nervous system development events, and lead to contact-dependent signalling through adjacent cells. Eph receptors are widely expressed in early development and rarely detected in adult tissues. EphB2 signalling has an important role in the development and structural organization of neurons. It regulates axon guidance in the developing nervous system (retinal ganglion cells, inner ear efferents) and maintains neuronal connectivity and excitatory synapse formation, specifically through interaction with NMDA receptors. EphB2 is also involved in angiogenesis, palate development and inner ear development through endolymph production. It is often overexpressed in various cancers (e.g., glioblastoma, colorectal cancer), where it promotes tumour progression, invasion, and migration through Epithelial-Mesenchymal Transition (EMT). EphB2 also appears to be act as a tumour suppressor protein (TSP). The active form of the protein kinase normally acts to inhibit tumour cell proliferation. EphB2 mutations have been found in prostate cancer. Most prostate cancers are adenocarcinomas that derived from acini of the prostatic ducts. K1019X mutation was significantly more common in African American probands. Over-expression of EphB2 has been frequently detected in both well-differentiated adenocarcinomas (10 of 13) and poorly differentiated adenocarcinomas (9 of 14). EphB2 expression restricts the invasiveness of colorectal cancer cells into ephrin-B1 expressing cell populations, thus segregating cancer cells from normal cells.
