Epidermal growth factor receptor represents one of the most intensively studied signaling molecules in cancer biology, serving as a master regulator of cell proliferation, survival, and differentiation. Phosphorylation at tyrosine 1092 marks a critical activation event in EGFR signaling, creating a docking site for downstream effectors that propagate mitogenic signals. Detecting this specific phosphorylation state enables researchers to monitor receptor activation dynamics in response to growth factors, therapeutic interventions, or oncogenic mutations.
This recombinant monoclonal antibody, generated against a synthetic phosphopeptide corresponding to the human EGFR Y1092 site, offers the reproducibility essential for phosphorylation studies where signal consistency between experiments is paramount. Because the antibody sequence is defined and produced recombinantly, you can expect uniform performance across lots, eliminating a common source of variability in sensitive phosphoprotein detection workflows.
Western blot validation demonstrates reliable detection of phosphorylated EGFR at the expected 170 kDa molecular weight across multiple human cell models. The antibody successfully identifies the target in A549 lung adenocarcinoma cells and HeLa cells following stimulation with either pervanadate phosphatase inhibitor or EGF ligand treatment, confirming its utility for detecting both pharmacologically stabilized and physiologically induced phosphorylation states. The recommended working dilution range of 1:500 to 1:5000 provides flexibility for optimization across different experimental conditions and sample types.
For researchers investigating receptor tyrosine kinase signaling, EGFR-driven oncogenesis, or therapeutic response mechanisms, this antibody delivers the specificity and consistency needed to generate publication-quality data in signal transduction studies.
