Fig. 6. ESI-MS/MS schematic of free (top) and PPC (either TriplatinNC or AH44) adducted (bottom) 5′-d(TCTCCCAGCGTGCGCCAT) at 100 and 120 V of collisional energy, respectively.34 Fragmentation of the glycosidic bonds is prevalent throughout the free, with the region of enhanced stability in teal. The associated fragment ions (w82–, w92–, and a9–a12 using standard McLuckey nomenclature) are absent in the adduct indicating the area of PPC binding.
