Abstract
Pass them on! Dithiobutylamine immobilized on a resin is a useful reagent for the reduction of disulfide bonds. Its ability to reduce a disulfide bond in a protein is enhanced greatly if used along with a soluble strained cyclic disulfide or mixed diselenide that relays electrons from the resin to the protein. This electron-relay catalysis system provides distinct advantages over the use of excess soluble reducing agent alone.
