Verwenden
5,5′-Dithiobis(2-nitrobenzoic acid) is a water soluble reagent mainly used for the derivatization of sulfhydryl groups.
Definition
ChEBI: An organic disulfide that results from the formal oxidative dimerisation of 2-nitro-5-thiobenzoic acid. An indicator used to quantify the number or concentration of thiol groups.
Allgemeine Beschreibung
5,5′-Dithiobis(2-nitrobenzoic acid) is also called DTNB or Ellman′s reagent. It is a water soluble reagent, which interacts with thiol groups, and can be used conveniently at neutral pH. Thiolate anion (RS
-) reacts with Ellman′s reagent (DTNB
2-), to produce 2-nitro-5-thiobenzoate anion (TNB
2-) and one mixed disulfide (R-S-TNB
-). TNB
2- has a high molar absorption coefficient, and absorbs at 412nm. This absorption is independent of pH, at pH> 7.3.
