Fig. 2. Steady-state emission titrations of Λ/Δ-[Ru(TAP)2(dppz)]2+ in the presence of (a) poly(dG-dC) (b) poly(dA-dT) (c) salmon-testes DNA. λexc = 435 nm; λem = 635 nm in 10 mM sodium phosphate buffer in H2O. For (a) plots are fitted to the McGhee–von Hippel equation. For (b) and (c) they are best fits using trend-line or interpolation methods. [Ru] = 20 μM (a), 8 μM (b and c).
