Redox potential of tcep
WebDTT is also a more powerful reducing agent with a redox potential (at pH 7) of −0.33 V, compared to −0.26 V for 2-mercaptoethanol. [7] 2-Mercaptoethanol is often used interchangeably with dithiothreitol (DTT) or the odorless tris (2-carboxyethyl)phosphine (TCEP) in biological applications.

TCEP is often used as a reducing agent to break disulfide bonds within and between proteins as a preparatory step for gel electrophoresis. Compared to the other two most common agents used for this purpose (dithiothreitol and β-mercaptoethanol), TCEP has the advantages of being odorless, a more powerful reducing agent, an irreversible reducing agent (in the sense that TCEP does not regenerate—the end product of T… Web22. máj 2024 · Note that the reduction of SetCys peptide 1 by TCEP was neglected since this reaction proceeds quickly at pH 7.2.
