Fig. 5. Cytoprotection by naphthoquinones (10 μM) versus their redox characteristics as determined by cyclic voltammetry in two cell lines RGC5 (a and b) and HepG2 (c and d). each data point is the average of 3 independent experiments with 6 replicates within each experiment for viability and 1 experiment for cyclic voltammetry (blue dots are for idebenone as a reference). Error bars were omitted for clarity.
