Fluorescence lifetime is a significantly more robust measurement of FRET, increased FRET transfer reduced donor lifetime, which can simply be recorded with TCSPC-FLIM. This type of measurement is advantageous as it requires low excitation light levels, it is oblivious to donor concentration, and in addition it provides information about the ratio of interacting versus non-interacting proteins TCSPC .
