Technical Data
EphB4 (Ephrin type-B receptor 4, HTK, MYK1, Tyro11, TYRO11)
Eph receptors belong to a family of receptor tyrosine kinases. Both ephrins, the ligands for Eph receptors, and Eph receptors are broadly expressed throughout the ectoderm, mesoderm, and endoderm of vertebrate embryos. The interaction of ephrins with the appropriate Eph receptor(s) has been implicated in a wide spectrum of functions in vertebrate morphogenesis, including the accurate migration of embryonic cells, formation of boundaries between structures (i.e. rhombomeres and somites), and the control of cytoskeletal changes which dictate cellular shape and adhesion during development. The EphB4 receptor, also known as Htk, Myk1, Tyro11 and Mdk2, was originally identified in CD34+ cells in the bone marrow and has since also been found in erythroid progenitor cells. The interaction between the EphB4 receptor and its ligand, ephrin B2, is critical for embryonic capillary morphogenesis. Upregulation of the EphB4 receptor has been observed in colon carcinoma, and in endometrial cancer4.

Suitable for use in ELISA and Western Blot. Other applications have not been tested.

Recommended Dilution:
ELISA: 0.1-1ug/ml
Western Blot: 1-3ug/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
