Tris(2-carboxyethyl)phosphine or TCEP is a potent, versatile, odorless, thiol-free reducing agent with broad application to protein and other research involving reduction of disulfide bonds. Because TCEP does not contain thiols, it does not have to removed from solutions before performing reactions involving maleimide labeling or cross-linking reagents. TCEP may be used as a substitute for DTT or 2-mercaptoethanol (2-ME) in reducing sample loading buffer for SDS-PAGE. One strategy for labeling antibodies involves reducing disulfide bonds in the hinge region of IgG molecules without also reducing those connecting heavy and light chains.
