Product Info
Background The EFGR family is a group of four structurally similar tyrosine kinases (EGFR, HER2/neu, ErbB-3, and ErbB-4) that dimerize on binding with a number of ligands, including EGF and transforming growth factor alpha (1&2). The 170 kDa epidermal growth factor receptor binds EGF which activates a tyrosine-specific protein kinase activity intrinsic to the receptor (3&4). Epidermal growth factor receptor overexpression is pronounced in virtually all squamous carcinomas and is also found in > or = 65% of large cell and adenocarcinomas. It is not expressed in situ by small cell lung carcinoma. Overexpression of EGFR is one of the earliest and most consistent abnormalities in bronchial epithelium of high-risk smokers (1).

Origin EGFR (EGFR1) is a mouse monoclonal IgG2b generated by immunizing mice with the human epidermoid carcinoma line A431. 
Product Details Each vial contains 100 g/ml of mouse monoclonal IgG2b EGFR DB138 (EGFR1), in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Immunogen Human epidermoid carcinoma line A431; epitope mapped between aa 6-273 of human EGFR 
Specificity This antibody is specific for the extracellular region of EGFR. This antibody does not react with erbB-2 (Her-2/Neu), erbB-3 and erbB-4.
