Fluorescence resonance energy transfer (FRET) experiment showing evidence for complex involving yyDNA sequence (entry 5, Table 3). Conditions: 100 mM NaCl, 10 mM MgCl2, 10 mM Na•PIPES (pH 7.0), 25 °C, with a total DNA concentration of 2 μM. The probe sequence was 5′-dGGAGAAGGTTTTTT-FAM, where FAM is 2-(6-carboxyfluorescein)-4-aminobutyl)-propyl-3-O-succinoyl-long chain alkylamino.
