| R0 values in angstroms (Å) represent the distance at which fluorescence resonance energy transfer from the donor dye to the acceptor dye is 50% efficient (Förster radius). Values were calculated from spectroscopic data as outlined (see Fluorescence Resonance Energy Transfer (FRET)—Note 1.2). | |||||
