Intracellular scavenging of tBHP-induced radicals by antioxidants. (a) Intracellular ROS production in SH-SY5Y cells treated with tBHP in the absence or presence of Proxison (10 μM), quercetin (100 μM), or myricetin (100 μM) was observed with CellROX® Deep Red. Scale bar: 40 μm. (b) The average intensity of CellROX® Deep Red (far red) fluorescence of cells in the five conditions were quantified with Volocity software. Bars represent the mean from four independent experiments with duplicate cover slips for Proxison, and two independent experiments for quercetin and myricetin. Error bars represent the SEM. ANOVA with the post-hoc Tukey test was performed to assess significant difference to vehicle-treated cells; **p < 0.01, ***p < 0.001.
