Poly(ethylene glycol) dissolves in many organic solvents and is readily soluble in aromatic hydrocarbons. It also slightly dissolves in aliphatic hydrocarbons.
Poly(ethylene glycol) is a chemical fusogen, which mediates the premature chromosome condensation induction in human and rat lymphocytes as well as in rodent spleen cells, and spleen and whole body cells of newborn mice.
Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. It enhances the refolding of extracted proteins. This enables characterization of crystallized proteins.
