TCEP (tris(2-carboxyethyl)phosphine) is a reducing agent frequently used in biochemistry and molecular biology applications. It is often prepared and used as a hydrochloride salt. TCEP is also available as a stabilized solution at neutral pH and immobilized onto an agarose support to facilitate removal of the reducing agent.
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 (DTT) and β-mercaptoethanol), TCEP has the advantage of being odourless. It is also more more hydrophilic and more resistant to oxidation in air than is DTT.
