Figure 5. Titration fluorescence response curve for binding of Fe-DOTA-Rev to 2-aminopurine-labeled Rev response element (RRE) RNA (AP-RRE) (18). Titration progress was monitored by use of the fluorescence emission at 371 nm, with excitation at 310 nm. Binding of AP-RRE by all other M-chelate-Rev complexes was studied in the same manner.
