Figure 6. Effect of SR on ROS levels determined in normoxic (A) and hypoxic (B) conditions on REH cells.
Cells were treated for 30–360 min with SR to analyze the oxidation state of the cell by using DCFH-DA as fluorogenic probe. Results are expressed as DCF (2′,7′-dichlorodihydrofluorescein) fluorescence (% of control) and are means ± SEM of four independent experiments.
