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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
