| Description | DEPMPO is a phosphorylated derivative of the widely used DMPO spin trap. It has been reported to produce spin adducts with increased stability particularly for the adduct of superoxide. [1] [2] [3] DEPMPO displays a detectable spin adduct signal at a concentration as low as 1 mM, as compared to 5 mM for DMPO.[3] A significant advantage of using DEPMPO in trapping superoxide radical is that the decomposition of DEPMPO/O2 - does not produce the OH adduct, which can be a drawback when using DMPO.
