Product Overview
Clone HOF-5 is a rabbit monoclonal antibody that recognizes epidermal growth factor receptor (gene EGFR) phosphorylated at Tyr1092 in human samples and is validated for Western blot, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 134.3 kDa, and the supplier reports an observed band at about 175 kDa.
Epidermal growth factor receptor (EGFR, also called ErbB1 or HER1) is a receptor tyrosine kinase activated by EGF, TGF-α and related ligands. Ligand binding triggers receptor dimerization and activation of RAS/MAPK, PI3K/AKT and other pathways that drive proliferation and survival, and EGFR is a major target in cancer research.

Immunogen
Synthetic phosphopeptide based on human EGFR Full-length sequence 1210aa around the phosphorylation site of Tyrosine 1092.
Reactivity Notes
The supplier lists reactivity with human. UniProt places epidermal growth factor receptor in the cell membrane, endoplasmic reticulum membrane, Golgi apparatus membrane and nuclear membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.
