DTT - 1,4-Dithiothreitol

Excellent reagent for maintaining SH groups in reduced state; quantitatively reduces disulphides. DTT is effective in sample buffers for reducing protein disulphide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulphide bridge of the cross-linker N,N′-bis(acryloyl) cysteamine to break apart the matrix of a polyacrylamide (Molecular Biology Grade)
