* DMTU = N,N'-dimethylthiourea. Disproportionation by catalase is also widely used for suppression of H2O2. † 0.28 M DMSO = 2% (v/v). The reactivity of OH• is so high that it can be argued that the actions of these reagents must be indirect. ‡ Trolox = 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid. § Ebselen = 2-phenyl-1,2-benzisoselenazol-3(2H)-one. ** MnTBAP = manganese(III)-tetrakis(4-benzoic acid)porphyrin. †† Tiron = 4,5-dihydroxybenzene-1,3-disulfonate. |
