Clone Host Grade Applications
Monoclonal Mouse Affinity Purified IP FC
EGFR is type I receptor tyrosine kinase with sequence homology to erbB-1, -2, -3, -4 or HER-1, -2, -3, -4. It binds to epidermal growth factor (EGF), transforming growth factor-a
(TGFa), heparin binding EGF (HB-EGF), amphiregulin, betacellulin and epiregulin. EGFR is overexpressed in tumors of breast, brain, bladder, lung, gastric, head and neck, esophagus, cervix, vulva, ovary and endometrium. It is predominantly present in squamous cell carcinomas.
Catalog #E3375-03

PurityPurified by Protein A affinity chromatography.
ImmunogenPurified EGFR from A431 cells. Cellular Localization: Cell membrane.
SpecificityRecognizes the 170kD (intact) and 145kD (VIII variant) forms of EGF receptor. The epitope maps to the extracellular domain of EGFR. Blocks EGF/TGFa-induced activation of EGFR (1,2). No effect on tyrosine kinase activity of the receptor. Inhibits the binding of antibody E3375-04 (-04X). Does not crossreact with erbB-2, erbB-3, or erbB-4. Species crossreactivity: Human and canine. Does not cross react with mouse or rat.
