DL-Dithiothreitol is a pivotal component used in the preparation of buffer which in turn is utilized in the platelet cytosol preparation.It is also important in isolation of RNA by using guanidinium salts and homogenisation of tissueand cells.

Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Clelands reagent. DTTs formula is C4H10O2S2 and the chemical structure of one of its enantiomers in its reduced form is shown at the right its oxidized form is a disulfide bonded 6-membered ring (shown below). The reagent is commonly used in its racemic form as both enantiomers are reactive. Its name derives from the four-carbon sugar threose. DTT has an epimeric (sister) compound dithioerythritol (DTE).
