ROS production in SW620 cells. (A) Cells were treated with baicalin at the indicated concentrations for 24 h, and intracellular ROS levels were quantitated with FACS analysis. FACS profiles for DHE in untreated (vehicle) or baicalin-treated cells (10⁴ cells/sample) are representative of the 3 experiments. (B) Relative percentage of cells that showed detectable ROS production. Control ROS⁺ cells were set at 100. Three experiments were performed in triplicate. * p < 0.05, compared to the control group.
