A High-Content Assay to Screen for Modulators of EGFR Function

Part of the Methods in Molecular Biology book series (MIMB, volume 1360)


Cell-based assays have the potential and advantage to identify cell-permeable modulators of kinase function, and hence provide an alternative to the conventional enzymatic activity-driven discovery approaches that rely on purified recombinant kinase catalytic domains. Here, we describe a domain-based high-content biosensor approach to study endogenous EGFR activity whereby EGF-induced receptor activation, subsequent trafficking, and internalization are imaged and quantified using time-dependent granule formation in cells. This method can readily be used to search for EGFR modulators in both chemical and RNAi screening; with potential applicability to other receptor tyrosine kinases.
