Sensitive Marker of the Cisplatin-DNA Interaction: X-Ray Photoelectron Spectroscopy of CL

Figure 4

The relative percentage of O–P (■), N=C (●), and C–N (▲) bonds for a cisplatin-oligo complex with ratio of 10 deconvoluted from the corresponding O 1s, N 1s, and C 1s peaks as a function of incubation time. The percentages were obtained from a similar Gaussian deconvolution procedure as shown in Figure 3.
