Application

Poly(ethylene glycol) has been used for histological, histochemical and immunohistochemical evaluation of in vitro cultured beads. It has been used for the fusion of cells.

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, required for the purification of biological materials. PEG also interacts with cell membrane, thereby resulting in cell fusion.
