Descrizione

Descrizione generale

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[1] can exist in the monomer and aqueous phases.[2]

Applicazioni

Poly(ethylene glycol) has been used:

• in cryopreservation of cell-laden multi-assay platforms (MAPs)[3]
• as a macromolecular crowder to study its effects on fluorescein isothiocyanate (FITC)-conjugated type-I collagen[4]
• as a model surfactant in surfactant formulations to evaluate the interfacial aggregation of antibody formulations in response to interfacial stress[5]

Azioni biochim/fisiol

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.[6]
