Figure 2.
Titrations of Ru(bpy)2dppz2+ with DNAs containing defects. Top: DNA sequences of matched, mismatched and abasic 27-mer duplex DNA (R denotes a tetrahydrofuranyl abasic site). Bottom: plots of the integrated emission intensity (λ x = 440 nm) of rac– (left),Δ– (middle) and Λ–Ru(bpy)2dppz2+ (right) (100 nM) upon increasing the concentration of DNA in 50 mM NaCl, 5 mM Tris, pH 7.5. Error bars indicate standard deviations in the measurements.
