5-（2-氨基乙基）二硫-2-硝基苯甲酸

5-（2-氨基乙基）二硫-2-硝基苯甲酸是Ellman试剂的更碱稳定的替代品，该试剂用于定量在碱性pH条件下的硫醇含量和酶促测定。实验证明与游离硫醇的反应方式与Ellman试剂类似，但稳定性大大提高。

5-(2-Aminoethyl)dithio-2-nitrobenzoic Acid is a more base-stable alternative to Ellman’s reagent used to quantify thiol contents and enzymatic assays under basic pH conditions. Experimentally shown to react with free thiols in a similar manner to Ellman’s reagent, but with dramatically improved stability.
