Palladium(II) Chelates as Biologically Active Metallo-Drugs: Synthesis, Characterization, DNA Binding, Electrochemical and In Vitro Cytotoxic Studies: Figure 2

Figure 2: Absorption spectra of complex [Pd(TAB)(H₂O)₂] (1) in Tris-HCl buffer upon addition of CT-DNA. [complex] = 20 μM, [DNA] = (0) [1], (30) [2], (40) [3], (50) [4], (60) [5], (79.8) [6] μM. Arrow shows the absorbance changing upon the increase of DNA concentration. Inst: plot of [DNA]/(ε_a − ε_f) versus [DNA] for the titration of CT-DNA.
