Reactive Oxygen Species (ROS) Fluorometric Assay Kit

The Reactive Oxygen Species (ROS) Fluorometric Assay Kit is a highly reliable and sensitive assay designed for the quantitative measurement of ROS in fresh tissue and live cell samples. ROS are highly reactive molecules that play a crucial role in various physiological and pathological processes, including oxidative stress, inflammation, and cellular signaling.

The assay works by utilizing the fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) to detect the presence of ROS. DCFH-DA is taken up by cells and is converted to dichlorofluorescein (DCFH) by intracellular esterase. DCFH is oxidized by ROS to the strong fluorescent DCF. The fluorescence of DCF (Ex/Em 502/525 nm) is directly proportional to the amount of ROS present in the sample.
