DTNB-Thiols Assay Kit

Cat.No. :

Kit-0311

Product Overview :

DTNB-Thiols Assay Kit is used for the quantitiation of Sulfhydryls (DTNB-Thiols).

Description :

The DTNB-Thiols assay kit measures sulfhydryl groups with the thiol reagent 5-5dithiobis[2nitrobenzoic acid] (DTNB), which forms the 5-thionitrobenzoic acid and a mixed disulfide. Under conditioins of oxidative stress, free sulfhydryls decrease and disulfides increase. Determination of the free thiol concentration in biological samples reflects the ability to detoxify lipid and other peroxides. Exocell's DTNB-Thiols assay can be used with a spectrum of biological samples including body fluids, tissue, and cell specimens.
To complete the assay, aliquots of standard or sample are reacted with rehydrated DTNB (Ellman's) reagent in microtiter wells. Absorbance is read at 405 nm using a reference filter of 630 nm. Concentration in samples is determined from the standard curve.

Stability :

Reconstituted Ellman's Reagent and DTNB Thiols are not stable and should be discarded after 1 day.

Storage :

Store this kit at 4°C.
