| Dithioerythritol Usage And Synthesis |
Chemical Properties | White solid | Uses | Reagent for maintaining ?SH groups in the reduced state; quantitatively reduces disulfides. | Uses | Reagent for the reduction of disulfide group. Prevents oxidation of sulfhydryl-containing proteins during SDS-polyacrylamide gel electrophoresis. Cleavage of disulfide bonds in proteins | Uses | 1,4-Dithioerythritol is a Michael reaction acceptor; inducers of enzymes that protect against carcinogenesis: reactivity with sulfhydryl groups. | Definition | ChEBI: The meso-diastereomer of 1,4-dimercaptobutane-2,3-diol; a sulfur-containing sugar derived from the monosaccharide erythrose; and an epimer of dithiothreitol. | reaction suitability | reagent type: reductant | Purification Methods | Crystallise DTE from ether/hexane and store it in the dark at 0o.
