Description and Uses

Free radicals are highly reactive, short-lived species. Spin traps react with radicals, forming stable adducts that can be further studied. DMPO is a commonly-used spin trap that reacts with O-, N-, S-, and C-centered radicals. This allows their characterization when used in association with electron spin resonance and immuno-spin trapping. DMPO is water-soluble, rapidly penetrates lipid bilayers, has low toxicity, and can be used in vitro and in vivo.

5,5-Dimethyl-1-pyrroline N-oxide has been used as a spin trapping reagent to detect free radicals in electron paramagnetic resonance (EPR) based reactions.
