In Vitro Antitumor Activity of a Keggin Vanadium-Substituted Polyoxomolybdate and Its ctDNA Binding Properties

Figure 4

The fluorescence spectra of mixed EB (100 μM) and ctDNA (220 μM) in the presence of different concentrations of PMo₁₀V₂ in PBS. It shows the fluorescence intensity changes upon increasing concentrations of PMo₁₀V₂ ([PMo₁₀V₂] = 0, 10, 20, 30, 40, 50, 60, 70, 80 μM). Insert: Stern-Volmer plot of the fluorescence titration data of EB-ctDNA with different concentration of PMo₁₀V₂ in PBS.
