The present invention relates to a composition comprising (i) a fluorescent-labelled fatty acid and (ii) a fatty acid binding compound, wherein (a) the fatty acid component of the fluorescent-labelled fatty acid binds the fatty acid binding compound and (b) the fluorescent component of the fluorescent-labelled fatty acid and the fatty acid binding compound interact to elicit FRET (Förster resonance energy transfer) effects. Moreover, the invention is directed to a method for identifying and/or characterizing a compound of interest by contacting a fluorescent-labelled fatty acid with a fatty acid binding compound under conditions that allow for binding and for FRET (Förster resonance energy transfer) effects, and then contacting the fluorescent-labelled fatty acid bound to the fatty acid binding compound with a compound of interest and determining the change in fluorescence. In addition, the invention pertains to corresponding kits of parts and uses of the compositions and methods.
