Spin-trapping reagent
WebThe EPR (ESR) spin trap reagent detects both superoxide and hydroxyl radicals produced by systems in vitro and in vivo. BMPO was developed as a spin trapping reagent that adducts superoxide and shows a much longer half-life (t 1/2 =23 min) than other spin trap reagents. It gives us reproducible and steady results.
