WebThiol-containing substances can be isolated selectively by covalent binding to an activated thiolated matrix via thiol-disulphide exchange to form a mixed disulphide bond. After washing away unbound material, the thiol-containing substance is eluted by reducing the disulphide bond. This technique is also known as covalent chromatography.
