Western blot analysis of Phospho-EGFR pTyr1148 in whole cell extracts of serum-starved A431 treated with 100ng/mL of EGF for 5 min (lanes 1 and 2) using a Phospho-EGFR pTyr1148 recombinant rabbit oligoclonal antibody (Product # 710213) at a dilution of 2ug/ml. To confirm specificity, competition was performed by preincubation with the phosphopeptide to inhibit antibody binding (lane 2). Samples were detected using chemiluminescence (ECL). Results show a band at ~175kDa.

This antibody is predicted to react with equine, mouse, rabbit and rat based on sequence homology.
ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale and purified with Protein A.
ABfinity™ oligoclonal antibodies comprise a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds—the sensitivity of a polyclonal antibody with the specificity of a monoclonal, all delivered with the consistency only found in a recombinant antibody. While functionally the same as a polyclonal antibody—recognizing multiple epitope sites on the target and producing higher detection sensitivity for low abundance targets when compared with monoclonal antibodies—an oligoclonal antibody has a known mixture of light and heavy chains. This exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Epidermal Growth Factor Receptor (EGFR) is a 175 kDa transmembrane glycoprotein belonging to tyrosine kinase superfamily. It acts as a receptor for epidermal growth factor (EGF) family proteins. Binding of EGFR to its ligands causes autophosphorylation of tyrosine kinase followed by activation of signal transduction pathways connected to cell proliferation and differentiation. Tyrosine 1068 present within the cytoplasmic domain of the receptor is a major autophosphorylation site that allows binding of Grb2 and activation of the Ras-Raf-ERK1 and ERK2 signaling pathway.
