WebOct 27, 2024 · The widespread occurrence of plastic has become a significant problem in the natural environment and may give rise to a range of deleterious impacts in biota, particularly where plastic particles overlap in size with that of the particles that are naturally ingested by filter-feeders. In this context, the effects of two particle sizes (10 μm and … WebJun 1, 2024 · The first approach uses the thiol reagent DTNB (5, 5'-dithiobis (2-nitrobenzoic acid)), also known as Ellman's reagent. DTNB is an aromatic disulfide that reacts with thiols by an exchange reaction to form a mixed disulfide of the protein and one molecule of TNB, which ionizes to the TNB2-dianion in water, producing a yellow color.
