TCEP (Tris [2-carboxyethyl] phosphine), a water soluble, odorless, non-toxic and stable protein reductan, is ta popular alternative to ß-mercaptoethanol and DTT (dithiothreitol). TCEP improves stability, increases effectiveness, and reduces proteins over a wider range of pH, including lower acidic pH's, compared to other reductants.

TCEP reduces stable disulfide bonds in less than 5 minutes at room temperature and is compatible with the protein alkylation reactions.

Available in convenient 1gm quantities.
