WebSuperoxide anion (O 2 −) is a reactive oxygen species that reacts quickly with nitric oxide (NO) in the vasculature. The reaction produces peroxynitrite and depletes the bioactivity of NO. This is important because NO is a key mediator in many important vascular functions including regulation of smooth muscle tone and blood pressure, platelet ... WebApr 1, 2024 · Measurement of Intracellular Reactive Oxygen Species (ROS) Levels The cells (5 × 10 4 /mL) were treated with lycopene for 24 h. For measurements of intracellular ROS, the cells were treated with 10 μg/mL of dichlorofluorescein diacetate (DCF-DA; Sigma-Aldrich) and incubated in 5% CO 2 /95% air at 37 °C for 30 min.
