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.

WebFeb 12, 2011 · This method is able to detect the original free radical after its reaction with the spin-trap reagent, creating a more stable compound. The linearity of a spin-adduct can distinguish whether it is able to scavenge a particular type of free radical. DEPMPO is a superior spin-trap reagent for scavenging superoxide radicals . WebN -tert-butyl-α-phenylnitrone (PBN) is a commonly used free-radical spin trap. It has been shown to reduce the number of emboli-induced cerebral microinfarctions in the rabbit cortex and prevent neoplasia by its radical scavenging activity and its ability to inhibit cyclooxygenase-2 activity.
