A simple luciferase assay for signal transduction activity detection of epidermal growth factor displayed on phage.

Studies on receptor-ligand interactions are important for the design of agonists or antagonists of natural ligands. We developed a luciferase reporter assay to screen epidermal growth factor receptor (EGFR) binding molecules rapidly for their ability to stimulate or inhibit signal transduction. Huma...
