General description

Poly(ethylene glycol) diglycidyl ether (PEGDGE) shows highly solubility in water. Hence, it easily undergoes hydrolysis followed by ring cleavage reaction in aqueous solution, yielding hydroxyl group. PEGDGE combines with proteins covalently or non-covalently. PEGDGE is widely used in chemical industries for cross linking and surface modifier.

Application

The high solubility of PEGDGE has been successfully employed to immobilize glucose oxidase, d-amino acid oxidase and glutamate oxidase. It may be used as a component for the development of microelectrode biosensors to detect hydrogen peroxide and nitric oxide.
