WebLomant’s reagent [ (dithiobis (succinimidylpropionate), or DSP]) is a homobifunctional NHS ester crosslinking agent containing an eight-atom spacer 12 Å in length ( Lomant and Fairbanks, 1976) (Thermo Fisher). It is symmetrically constructed around a central disulfide group that is cleavable after conjugation with typical disulfide reducing ... WebApr 6, 2024 · In this study, a typical tea polyphenol epicatechin (EC) was investigated for its impact on the oxidative stability of whey protein isolate (WPI) in a fish oil-fortified emulsion. The oil-in-water emulsion system consisted of fish oil (1%, w/w), WPI (6 mg/mL), and EC (0.1, 1, and 2 mM), and the oxidation reaction was catalyzed by Fenton’s reagent …

The method described is based on the development of a yellow colour when 5,5′-dithiobis (2-nitrobenzoic acid) (Ellman reagent, DTNB) is added to sulphydryl compounds. The colour that develops is fairly stable for about 10 min and the reaction is little affected by variation in temperature.
WebWe previously reported on a method for the facile removal of 4-methoxybenzyl and acetamidomethyl protecting groups from cysteine (Cys) and selenocysteine (Sec) using 2,2'-dithiobis-5-nitropyridine dissolved in trifluoroacetic acid, with or without thioanisole.
