Description

Reagent for determination of sufhydryl groups.5,5'-dithiobis-(2-nitrobenzoic acid) is widely utilized as a non-fluorescent probe to quantify the number or the concentration of thiol groups in a sample. It acts as a cleavable cross-linking agent. It finds an important application as a sensitive reagent for determining free sulfhydryl content in proteins, peptides, and tissues. It is also employed in high-performance liquid chromatography (HPLC) to determine the alkylthiol content.
