Caught in the act: The FRET-Capture approach exploits a bound solvatochromic fluorophore, 4-N,N-dimethylamino-1,8-naphthalimide, as a FRET donor in both inter- and intramolecular energy transfer. A unique feature of this method is the additional level of signal selectivity as the FRET signal is only turned on when the donor is specifically bound to the protein of interest, eliminating high background and false positive signals.
