Panel A: HaCaT cells; Panel B: A2780 cells; Panel C: A2780CIS cells. Cells were treated identically as for Figure 1, but were given a sham irradiation. These experiments were conducted in parallel with the phototoxicity experiments (ie. each complex was tested in a “light” & “dark” plate). Data are the mean ± SE of 4/6 monolayers from 2/3 independent experiments. Figure subdivided by complexes a) 7c, 8c, 9c; b) 7t, 8t, 9t, 10t, 11t; c) 1c 4c 5c 6c; d) 1t, 2t, 3t.
