General description

1,4-Dithiothreitol (DTT or Cleland's reagent) reduces disulfide bonds in proteins, leading to loss of native conformation
DTT is not stable in solution and should be prepared in small aliquots prior to use; the use of EDTA in the solution can increase the half-life of DTT
Typically used at a final concentration of 0.1M for protein stabilization; recommended to create a 1M stock

Applications

Protects thiol groups from oxidation and acts as a chemical chelator in solution; maintains proteins in the denatured state
Common applications include SDS-page electrophoresis and protein isolation
