General descriptionThis cell line was derived from ATCC catalog No. CCL-185.
ApplicationThe EGFR Biosensor cell line consists of the SH2 domain of the adaptor protein Grb2 fused to GFP. The biosensor was transduced into the A549 cell line and a stable cell line was cloned from a single cell. Within minutes after stimulation of the cell line with EGF, the biosensor shows robust redistribution towards the cell membrane and subsequent internalization through endocytosis. The internalization kinetics of the sensor-receptor complex can be quantified by image analysis software to count granules. The reporter response is highly selective as it can be induced only by specific EGFR ligands and is abolished by a selective inhibitor of EGFR, Tyrphostin AG 1478.
