Description
Dithiothreitol is useful for stabilizing sulfhydryl containing enzymes. 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. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM).
DTT has been used:
- As one of the reactants in the reduction and alkylation of αs1-Casein, the major allergen of cow′s milk
- As a component of medium for the demembranation and reactivation of spermatozoa
- To maintain stability of the enzyme as thiol effectively protects the active sites of the biocatalyst
- As a reducing agent to test the specificity of the reaction of N-Ethylmaleimide with sulfhydryl groups
