Using GFP in FRET-based applications

Trends Cell Biol. 1999 Feb;9(2):57-60. doi: 10.1016/s0962-8924(98)01434-2.


The use of green fluorescent protein (GFP) is a powerful technology that has recently enabled investigators to study dynamic molecular events within living cells. One method for detecting molecular interactions involves fluorescence resonance energy transfer (FRET) between two GFPs or between GFP and a second fluorophore. This review summarizes the use of GFP for FRET and illustrates the theme with specific examples on how GFP has been employed as an intracellular molecular sensor.
