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 (I12) is provided as an affinity purified rabbit polyclonal antibody, raised against a peptide mapping to a sequence near the carboxy terminus of human EGFR. 
Product Details Each vial contains 200 g/ml of affinity purified rabbit IgG EGFR (I12) DB050, in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Competition Studies A blocking peptide is also available, DB050P, for use in competition studies. Each vial contains 0.100 mg of peptide in 0.5 ml PBS with 0.1% sodium azide and 100 mg BSA. 
Form 200 g/ml rabbit polyclonal IgG in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Immunogen Synthetic peptide mapping to a sequence near the carboxy terminus of human EGFR. 
Specificity EGFR (I12) DB050 reacts with EGFR of mouse, rat, and human origin by western blotting, immunoprecipitation, and immunohistochemistry (including paraffin-embedded sections). Western blotting starting dilution: 1:200. A431 lysates can be used as a positive control. 
Use
Western blot analysis of EGFR expression in A431 whole cell lysates.
