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 (TGF-a), heparin binding EGF (HB-EGF), amphiregulin, betacellulin and epiregulin. EGFR is over expressed 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.
Applications
Suitable for use in ELISA, Immunofluorescence, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications have not been tested.
Recommended Dilutions
Western Blot: 0.5-1ug/ml for 2 hrs at RT. Suitable for Western blot of extracellular domain of EGFR. Immunoprecipitation (Native only): 2ug/mg protein lysate. Use Protein G. Immunohistochemistry (Formalin/ Paraffin): 2-4ug/ml for 30 mniutes at RT. Staining of formalin-fixed tissues requires digestion with Protease XXV at 1mg/ml PBS for 5 min at 37°C. (Note: E3375-06B/ E3375-06BX are more suitable for use in IHC). Optimal dilutions to be determined by the researcher.
Positive Control
A431 cells, placenta or squamous cell carcinoma.
