Reducing agents can be used to disrupt, or reduce, disulfide bonds in peptides and proteins. Disulfide reducing agents include tris (2-carboxyethyl) phosphine hydrochloride (TCEP), beta-mercaptoethanol (BME), and dithiothreitol (DTT). Usage of these agents is important for analyzing individual proteins.
