DTT (DITHIOTHREITOL) Usage And Synthesis

Description

Dithiothreitol (DTT) from is offered in a convenient 192.8 mg lyophilized format, allowing for preparation of a fresh stock solution. This DTT reagent contains no detectable DNase or RNase activity and is suitable for use in molecular biology or protein biochemistry applications that require reduction of protein disulfide bonds.SDS-PAGE sample buffers are routinely supplemented with 10-50 mM DTT to cleave protein disulfide bonds. Lower concentrations of DTT are routinely used to stabilize enzymes or other proteins that posses free sulfhydryl groups, which is useful in chromatin immunoprecipitation (ChIP) assays.
