Fig. 4. Cell viability after treatment with 100 μM 8, 100 μM CuSO4, 200 μM ligand, 500 μM sodium ascorbate in 10/90 (v/v) methionine-free DMEM/PBS for 10 minutes. Cell viability is normalized with the absorbance of the negative control of cells without any treatment. Error bars represent the standard deviation of the data from three samples.
