Epidermal growth factor receptor (EGFR) is a 170kDa transmembrane glycoprotein receptor tyrosine kinase that, activated by epidermal growth factor (EGF), affects cell growth and differentiation (1). Binding of EGF or TGF alpha to EGFR activates tyrosine kinase activity of the receptor (2). The carboxy terminal tyrosine residues on EGFR, Tyr 1068, Tyr 1148, and Tyr 1173, are the major sites of autophosphorylation, which occurs as a result of EGF binding (3). Once activated, EGFR phosphotyrosines Y-1068 and Y-1173 mediate the binding of Grb2 to the EGFR. Addtionally, phosphotyrosine Y-1173 is a major binding site for SHC on the EGFR (4). Applications: Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. 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. Manufactured incorporating RabMAb(R) technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
