Figure 1

Δ-Rh(bpy)2(chrysi)3+ (left) along with sequences, melting temperatures (Tm), and binding affinities (KB) for the duplexes. Tm's were determined for 1 μM DNA in buffer (50 mM NaCl, 10 mM NaPi, pH 7.1). Photocleavage titrations of DNA (1 μM) in buffer and variable Rh(bpy)2(chrysi)3+ (0–10 μM) were employed to obtain site-specific binding constants (see Supporting Information). “R” denotes tetrahydrofuranyl abasic site; “–” indicates no nucleotide. Melting temperatures are accurate within 1 °C.
