1,4- dithioerythritol or dithioerythritol (DTE) is a chemical compound which is derived from the sugar alcohol erythritol by substituting the oxygen atoms in the terminal hydroxyl groups by sulfur atoms. The dithioerythritol is the diastereomer of dithiothreitol (DTT), and is - as well as erythritol - seen stereochemically a meso compound. DTE is a good reducing agent such as DTT, and also cleave disulfide bonds in proteins, which is why it is used, inter alia, on SDS -PAGE in the sample buffer.
