Paper Abstract

Fluorescence resonance energy transfer (FRET) has been widely used in biology in recent years, and permits high spatial resolution assays of protein-protein interactions in living cells. Here, we first use the FRET technique to real-time observe the binding of EGF to EGFR on the surface of A549 cells and EGFR-GFP-ldlA7 cells, and continuously monitor this reaction for 1 hour. In addition, this is the first direct evidence that FRET occurred between different proteins which are in the intramembrane and extramembrane, respectively.
