In this procedure, DTNB, a symmetric aryl disulfide, reacts with the free thiol to give a mixed disulfide plus 2-nitro-5-thiobenzoic acid (TNB) which is quantified by its absorbance at 412 nm. We observed that the presence of NO during the determination of SH groups in a reaction ...

5,5′-dithio-bis-(2-nitrobenzoic acid), also known asDTNB(Tietze, 1969). Ellman's reagent reacts with a freesulfhydryl(thiol) group to yield a mixeddisulfideand 5-nitro-2-thiobenzoic acid (TNB; λ max at 412nm), a measurable, yellow-colored product in a short reaction time. Using ...
DTNB reacts with the free sulfhydryl side chain of cysteine to form an S-S bond between the protein and a thionitrobenzoic acid (TNB) residue. The main advantage of DTNB over alternative reagents (e.g., N-ethylmaleimide or iodoacetamide) is in the selectivity of this reagent and in the ...
conditions (pH 7-8), the 2-nitro-5-thiobenzoate anion (TNB 2-) gives an intense yellow color at 412 nm.3 The optimal molar extinction coefficient value for TNB 2- has been somewhat controversial. The original work by Ellman 4 cited a value of 13,600 M -1 cm -1 . Since this ...

DTNB reacts with a free sulfhydryl group to yield a mixed disulfide and 2-nitro-5-thiobenzoic acid (TNB). The target of DTNB in this reaction is the conjugate base (R—S-) of a free sulfhydryl group. Therefore, the rate of this reaction is dependent on several factors: (1) the ...
