WebQuantification of free protein thiol groups may be performed by derivatization with 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB), also called Ellman’s reagent (Ellman 1959).The assay is based on the formation of a coloured thiolate ion complex that can be detected spectrophotometrically at 412 nm with an extinction coefficient of 13 600 mol −1 cm −1 … WebMar 15, 2024 · Ellman's spectrophotometric thiol test, albeit less sensitive in contrast, is quick and easy to use, making it more common for quantifying sulfhydryls. By comparing a sample's sulfhydryl groups to a standard curve made up of known amounts of a sulfhydryl-containing substance like cysteine, sulfhydryl groups can be calculated in a sample.
