Description :Rabbit Polyclonal Antibody
Specificity :Recognizes the EGFR protein
Cited Applications :WB
Cross Reactivity :Western blot EGFR from human and mouse cells
EGFR from other species may also be detectable.
Immunogen :Synthetic peptide corresponding to amino acids 1090- 1094 of human EGFR (protein accession number P00533)

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For optimal performance, avoid repeated handling and multiple freeze/thaw cycles.
Sample Data :Representative western blot with Anti-EGFR (1:1000) using 3 μg, 10 μg and 30 μg of HeLa cell lysate.
Scientific Background :EGFR is the receptor for members of the EGF family and is a transmembrane glycoprotein that has tyrosine kinase activity. Binding of epidermal growth factor to EGFR induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation, differentiation, motility, and cell survival (1). Activation of EGFR triggers mitogenic signaling in gastrointestinal mucosa, and its expression is upregulated in colon cancers and most neoplasms (2). Activation of EGFR triggers activation of the ERK-signaling pathway in normal gastric epithelial and colon cancer cell lines. Inactivation of EGFR with selective inhibitors significantly reduces ERK2 activation, c-fos mRNA expression and cell proliferation.
