Reactive Oxygen Species (ROS) Detection / Nitric Oxide Detection
Reactive oxygen species (ROS) are chemically reactive compounds containing oxygen. The sequential reduction of oxygen through the addition of electrons leads to the formation of a number of ROS including hydrogen peroxide (H2O2), hydroxyl radical (• OH), tert-butyl-hydroperoxide (TBHP), hypochlorous acid (HOCl), superoxide anion (O2 • ), nitric oxide (NO• ) and peroxynitrite anion (ONOO). ROS are produced during a number of physiological and pathological processes. Many diseases are caused by excessive ROS as a result of an imbalance between radical-generating and radical-scavenging systems, a condition called oxidative stress.
