Target description

180 kDa

Analysis Note

A431 cell lysate, human cervical carcinoma.

Included Positive Antigen Control:
Catalog # 12-305, 3T3/A31 Cell Lysate. Add 2.5 µL of 2-mercaptoethanol/100 µL of lysate and boil for 5 minutes to reduce the preparation. Load 20 µg of reduced lysate per lane for minigels.

General description

The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer. EGFR (epidermal growth factor receptor) exists on the cell surface and is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor α (TGFα). Upon activation by its growth factor ligands, EGFR undergoes a transition from an inactive monomeric form to an active homodimer. In addition to forming homodimers after ligand binding, EGFR may pair with another member of the ErbB receptor family, such as ErbB2/Her2/neu, to create an activated heterodimer. EGFR dimerization stimulates its intrinsic intracellular protein-tyrosine kinase activity. As a result, autophosphorylation of five tyrosine (Y) residues in the C-terminal domain of EGFR occurs.


Ovalbumin conjugated synthetic peptide (ETKPNGIFKGPTAENAEYLRVAPPSSEFIGA) corresponding to amino acids 1156-1186 of the processed mouse EGF receptor (EGFR) C-terminal domain (Accession number Q01279). The immunizing sequence shares 28/31 identity with the human EGF receptor sequence.
