WebA method for assaying glutathione reductase (GSH; EC 1.6.4.2) in crude plant extracts is described. The method is based on the increase in absorbance at 412 nm when 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB) is reduced by GSH. The effects of the following parameters on the assay were tested: various … WebThe DTNB reduction assay is inexpensive, simple, and (because of the high ε 412 value of TNB and the stoichiometry of the reaction) sensitive; it lacks, however, specificity. For …
