Thermo Scientific Pierce DTNB （Ellman's Reagent） reacts with sulfhydryl groups to yield a colored product, providing a reliable method to measure reduced cysteines and other free sulfhydryls in solution.
Ellman's Reagent （5,5'-dithio-bis-[2-nitrobenzoic acid]） is used to estimate sulfhydryl groups in a sample by comparing to a standard curve of a sulfhydryl-containing compound such as cysteine. Alternatively, sulfhydryl groups can be assayed using the extinction coefficient of TNB （14,150M-1cm-1 at 412nm）. Ellman's Reagent has been used for applications other than sulfhydryl estimation, such as for determining alkylthiols by HPLC using a pre-column derivatization procedure and to study thiols in the active site of several enzymes.
Highlights:
- Determine availability of sulfhydryls for labeling or crosslinking applications
- Assay by measuring the absorbance at 412nm or using cysteine as a standard
- Temporarily block sulfhydryls to perform chemistries on other protein functionalities
