DL-Dithiothreitol Usage And Synthesis

DL-Dithiothreitol Usage And Synthesis

Chemical Properties	White solid
Uses	Reagent for the quantitative reduction of disulfide group. Prevents the oxidation of cholecystokinin during its extraction from brain and duodenal tissues. Cleavage of disulfide bonds in proteins.
Uses	DTT is a cell permeable protective agent for Thiol groups.
Purification Methods	Crystallise DTT from ether and sublime it at 37o/0.005mm. It should be stored at 0o. [Beilstein 1 III 2360.]
General Description	An excellent reagent for maintaining SH groups in reduced state; quantitatively reduces disulfides. DTT is effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM).
