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][2]
- Application: Poly(ethylene glycol) (PEG) has been used to study PEG-β lactoglobulin interaction.[3] It has also been used to study the interaction of serum albumins with PEG.[4]
