EGF Receptor / EGFR Antibody

SKU: orb606695

Description

Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, amphiregulin, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16, activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling. Also phosphorylates MUC1 and increases its interaction with SRC and CTNNB1/beta-catenin. [UniProt]

Western blot testing of human A431 cell lysate with recombinant EGF Receptor antibody. Expected molecular weight: 134-180 kDa depending on glycosylation level.

SDS-PAGE analysis of purified, BSA-free recombinant EGF Receptor antibody (clone GFR/2968R) as confirmation of integrity and purity.

IHC testing of FFPE human placenta with recombinant EGF Receptor antibody (clone GFR/2968R). Required HIER: boiling tissue sections in 10mM citrate buffer, pH6, for 10-20 min and allow to cool prior to testing.

Analysis of HuProt (TM) microarray containing more than 19, 000 full-length human proteins using recombinant EGF Receptor antibody (clone GFR/2968R). These results demonstrate the foremost specificity of the GFR/2968R mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
