Description

5,5'-Dithiobis (2-nitrobenzoic acid), referred to as DTNB, is a sensitive reagent for the determination of sulfhydryl groups in proteins, peptides and tissues. It is also used for the detection of organophosphorus pesticide poisoning (cholinesterase determination) and is widely used in biochemistry the study.

Use

DTNB and sodium bicarbonate are mixed in a certain ratio and used as a developer for the product acetylcholine. It is usually used for pesticide residue detection. It reflects the inhibition rate of enzyme through absorbance, and is finally used to preliminarily judge whether the pesticide exceeds the standard.
