Details:

5,5′-Dithiobis(2-nitrobenzoic acid) (DTNB), also called Ellman’s reagent, is a biochemical compound used to quantify free thiol (-SH) groups in proteins, peptides, or other molecules.

Mechanism: Reacts with thiols to release 2-nitro-5-thiobenzoate (TNB), a yellow-colored product detectable at 412 nm (absorbance).

Applications: Measures cysteine residues, enzyme activity (e.g., acetylcholinesterase), and antioxidant levels (e.g., glutathione).

Features: Water-soluble, forms a 1:1 molar ratio with thiols, and has a high extinction coefficient (~14,150 M?¹cm?¹).

Usage: Common in spectrophotometric assays for thiol quantification.

Safety: Irritant—handle with protective gear. Critical for studying redox states and protein structure.
