General description

The gene epidermal growth factor receptor (EGFR) is mapped to human chromosome 7p12. It belongs to receptor tyrosine kinase family. The protein is mainly localized in the plasma membrane.


Epidermal growth factor receptor precursor recombinant protein epitope signature tag (PrEST)


Anti-EGFR antibody produced in rabbit is suitable for use in epitope mapping to study the antibody cross-reactivity with a multi-target fragment library.
Anti-EGFR antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit

Biochem/physiol Actions

Epidermal growth factor receptor (EGFR) plays an important role in cell proliferation, survival, and differentiation. Interaction between EGFR and its ligands results in stimulation of several transduction pathways including the RAS/RAF/MEK/MAPK, PLC-γ/PKC, PI3K/AKT, JAK/STAT, and NF-κB cascades. Presence of ligand stimulates EGFR phosphorylation. This event subsequently recruits ubiquitin ligase, CBL, to EGFR. Activated EGFR-ligand complex is removed from the cell surface via endocytosis and is degraded in the lysosomes to attenuate the signaling. EGFR hyper-phosphorylation is linked to cell proliferation and thereby tumor development. EGFR is associated with a number of human solid tumors, including lung, breast, prostate, bladder, colon, head and neck, ovarian and salivary duct carcinomas.
Density-enhanced phosphatase-1 (DEP1) dephosphorylates and thereby stabilizes EGFR. The transmembrane protein LRIG1 and suppressors of cytokine signaling-5 (SOCS5) binds and destabilizes EGFR. Protein tyrosine phosphatase PTPN3 and PHD3 promotes EGFR endocytic degradation.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST78874.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
