Fig. 3From: Molecular interaction and cellular studies on combination photodynamic therapy with rutoside for melanoma A375 cancer cells: an in vitro studyThe cell viability of A375 melanoma cancer cells treated with various concentrations of MB and rutoside. Rutoside [50 µg/mL for 4 h (a, b) and 24 h (c, d)] and then MB treatment was performed for 1 h and keeping in darkness or with red irradiation (660 nm) for 90 s (PDT). The results are expressed as mean ± SD (n = 3), *P < 0.05 (compared to the control (untreated) group. R rutosideBack to article page
