DL-Dithiothreitol, 99%

Dithiothreitol, DTT or Cleland''s reagent is a small-molecule redox reagent. In molecular biology it is used as a reducing agent, providing thiolated DNA with protection against dimerisation and therefore increasing the efficiency of coupling reactions. DTT is also used to reduce disulfide bonds in proteins, giving it a role in applications such as polyacrylamide gel electrophoresis.
