Description: DMPO (5,5-Dimethyl-1-pyrroline N-oxide) is a kind of water-soluble nitric oxide spin trap, which allows the measurement of oxygen-centered free radicals in biological systems at room temperature using electron spin resonance. It has a high reaction rate constant for superoxide and hydroxyl radicals and distinguishes simultaneously among a variety of important biologically generated free radicals.
