Fig. 5. Photoinduced binding of [1]Cl (a) and [2]PF6 (b) to pUC19 plasmid DNA. The lanes correspond to (1) lambda DNA MW marker, (2) dark DNA only control, (3) irradiated DNA only control, (4) dark 50 : 1 BP : MC control, (5–9) 5, 15, 30, 45, and 60 min irradiated 50 : 1 BP : MC samples, respectively. The bands of the lambda MW marker correlate to 23, 9.4, 6.6, 4.4, 2.3, and 2.0 kpb. The dark DNA control bands are labelled according to the form, linear dimer (LD), open circular (OC), and supercoiled (SC).
