설명

일반 설명

Poly(ethylene glycol) (PEG), a linear polyether of ethylene glycol (ethane-1,2-diol), is soluble in water, benzene, ethanol, acetonitrile, and dichloromethane. However, it is insoluble in diethyl ether and hexane. This non-ionic polymer can exist in the monomer and aqueous phases.

애플리케이션

Poly(ethylene glycol) has been used:

• in cryopreservation of cell-laden multi-assay platforms (MAPs)
• as a macromolecular crowder to study its effects on fluorescein isothiocyanate (FITC)-conjugated type-I collagen
• as a model surfactant in surfactant formulations to evaluate the interfacial aggregation of antibody formulations in response to interfacial stress

생화학적/생리학적 작용

Poly(ethylene glycol) (PEG) is used in several applications including medicine. This polymer occurs as a preservative and is used in biomedical applications like drug delivery systems, biosensing, and tissue engineering. PEG is also used in cosmetic ointments and creams. It is used as a binding and dispersing agent in chemical and other industries.
