     Thiopropyl Sepharose™ 6B (GE Healthcare) has been used widely over several decades to reversibly bind biological molecules containing the sulfhydryl groups—the 2-thiopyridyl disulphide group of the sepharose matrix reacts with a molecule containing a free thiol to form a mixed disulfide; during the reaction thiopyridone is formed while the bound target molecule is released by addition of a reducing agent.
