Anti-Human EphA2 (F2-27) ColorWheel^® Dye-Ready mAb

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Ephrin type-A receptor 2 (UniProt: P29317; also known as EC: 2.7.10.1, Epithelial cell kinase, Tyrosine-protein kinase receptor ECK) is encoded by the EPHA2 (also known as ECK) gene (Gene ID: 1969) in human. Ephrin type-A receptor 2 (EphA2) is a homodimeric single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-23), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 24-537), a short transmembrane domain (aa 538-558), and a cytoplasmic domain (aa 559-976). It is expressed in brain and glioma tissue and in glioma cell lines. It is also highly expressed in tissues that contain a high proportion of epithelial cells. Its levels are up-regulated by UV irradiation via a TP53-independent, MAPK-dependent mechanism. EphA2 serves as a receptor tyrosine kinase that binds promiscuously membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. It is involved in the regulation of migration, integrin-mediated adhesion, and in proliferation and differentiation of cells. EphA2 is phosphorylated on tyrosine residues upon binding and activation by EFNA1. Phosphorylation on tyrosine 588 and 594 is reported to be essential for binding VAV2 and VAV3 while phosphorylation on Tyr 735 and Tyr 930 are required for binding PI3-kinase p85 subunit. Overexpression of EphA2 is reported in murine models of skin tumors. Inflammatory cytokines are reported to promote RSK-dependent phosphorylation of EphA2 at serine 897 and this RSK-EphA2 axis might contribute to cell motility and promote tumor malignant progression. Two isoforms of Ephrin type-A receptor 2 have been described that are produced by alternative splicing. This ColorWheel^® Dye-Ready monoclonal antibody was developed using our Cat. No. MABS2026; Anti- Anti-EphA2, clone F2-27. (Ref.: Zhou, Y., et al. (2015). Nat. Commun. 6; 7679; Guo, H., et al. (2006). Cancer Res. 66(14); 7050-7058).
