Description
- General description: Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion.[1] It exhibitsstealth effect, prolonged blood circulation and excellent biocompatibility. PEG has an ability to elicit hypersensitivity reactions via stimulating complement pathway.
- Application: Poly(ethylene glycol) has been used:as a constituent in the preparation of liquid desiccant solutions[2]as a precipitating agent and additive in protein crystallization[3][4]as a representative biocompatible polymer to decipher its interactions with cellular system at molecular level[5]
