Descrição geral

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.

Aplicação

Poly(ethylene glycol) has been used for concentrating HIV (human immunodeficiency virus). It has been used in the solution prepared to study CD (circular dichroism) spectra of nisin.
