Cat.No. 3415 - DMPO | C6H11NO | CAS No. 3317-61-1
Description: Nitric oxide spin trap; measure oxygen-centered free radicals
Chemical Name: 3,4-Dihydro-2,2-dimethyl-2H-pyrrole 1-oxide

Biological Activity

Water soluble nitric oxide spin trap; allows the measurement of oxygen-centered free radicals in biological systems at room temperature using electron spin resonance (ESR). Has a high reaction rate constant for superoxide and hydroxyl radicals, and distinguishes simultaneously among a variety of important biologically generated free radicals.
