ICL formation upon UV-irradiation at 350 nm for 50 min. Phosphorimage autoradiogram of 20% denaturing PAGE analysis of the ICL products: lane 1, unmodified duplex 6; lanes 2–5, duplexes 7 and 9–11 containing coumarin-modified ODNs hybridized with opposing sequences containing A, C, T, and G; lanes 6–9, duplexes 12–15 containing coumarin-modified ODNs hybridized with opposing sequences containing only As, Ts, Gs, and Cs in opposite sequences.
