Synonyms: Thiol Reactive Agarose Beads, Activated thiol Sepharose
Thiopropyl Resin is used in purification of thiol group containing proteins, molecules and enzymes. The thiol-containing molecules are reversibly immobilized on the resin. When the sample to be purified is passed through the resin, thiol- containing biomolecules bind to the resin to form mixed disulfides and release2-thiopyridone. The bound molecule is eluted by addition of reducing agent such as DTT or 2-mercaptoethanol.
