一般說明

聚乙二醇(PEG)是一种聚醚化合物,用于作为化妆品,药品及食品的添加剂。它包含重复的乙二醇[-(CH2CH2O)n]单元。

應用

聚乙二醇被用于:
  • 作为威斯康星大学(UW)冷藏溶液的组分,在温度变化期间稳定肝细胞的细胞膜
  • 作为过冷液的组分,研究大鼠移植肝脏的过冷保存技术,防止低温损伤
  • 制备用于制造多细胞球体(MCS)培养物的水相

生化/生理作用

聚乙二醇(PEG)是一种合成高分子,被用作生物偶联和纳米药物延长血液循环时间,提高药物疗效的金标准。它通过防止冰结晶来充当冰调节剂,这对细胞膜是有益的。PEG可防止细胞低温损伤,如脂质过氧化和细胞膜损伤。PEG-偶联药物被认为可在人体上安全使用,并得到美国食品和药品监督局(FDA)批准。PEG在许多生物医学应用,包括生物传感器,成像和组织工程。它还排斥蛋白质吸附和降低肝脏摄取,这有助于包裹纳米颗粒。
