Figure 5

Trypan blue viability assay to assess the effect of Hyp-PDT versus AlPcS4Cl-PDT when cells were treated with Hyp or AlPcS4Cl for 24 hrs followed by laser irradiation at wavelengths 594 and 682 nm, respectively. Untreated A375 (cell + 0 PS, 0 LI) were compared with those treated with 2.5 μM PS, 5 J/cm2 and those treated with 2.5 μM PS + 1, 2.5, 5, and 10 J/cm2.
