Fluorescence Resonance Energy Transfer (FRET) imaging is a powerful microscopy technique that overcomes some of the usual limitations of light microscopy to allow researchers to visualize and quantify protein associations under physiological conditions in individual cells. Also known as Förster Energy Transfer (FET), FRET utilizes radiationless energy transfer between proteins tagged with mutant forms of jellyfish green fluorescent proteins (GFP). FRET imaging can be done using wide field, confocal, and two-photon microscopy systems.

With any new or developing technology comes implementation challenges and a scientific knowledge base dispersed among many researchers and institutions. The goal of this site is to facilitate communication among researchers involved with FRET. FRETImaging.org is currently a work in progress, so check back frequently for updates or contact the webmaster to volunteer or make suggestions.
