compound introduction
聚乙二醇二缩水甘油醚(PEGDGE)具有良好的水溶性。因此，它很容易水解，然后在水溶液中发生环裂解反应，生成羟基。聚乙二醇与蛋白质共价或非共价结合。 聚乙二醇广泛应用于化工行业的交联和表面改性。聚乙二醇的高溶解性已成功地应用于葡萄糖氧化酶、d-氨基酸氧化酶和谷氨酸氧化酶的固定化。它可以作为微电极生物传感器的一个组成部分，用于检测过氧化氢和一氧化氮。 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.
