General description

聚乙二醇(PEG)是乙二醇聚合物,具有亲水性。PEG具有高水合能力并且结构灵活。由于PEG具有生物相容性并且结构中不存在空间位阻,因此,它在用作药物结合物方面具有优势。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

聚乙二醇已被用于:
  • 酵母的转化缓冲液
  • 作为登革病毒分离缓冲液的成分
  • 慢病毒颗粒的浓缩
  • 疱疹病毒核出口复合物(NEC)的结晶化

Biochem/physiol Actions

美国食品和药品监督管理局(FDA)批准PEG用作药物结合物,它是非免疫原性且安全的。PEG被广泛用作生物化学和分子生物学实验的试剂。PEG结合改善了糖尿病药物格列齐特的溶解度和溶出度。它被用于碳纳米管官能化。在富含单宁的树叶中,PEG 8000的存在可提高代谢能(ME)含量和气体产生。
