Application: | 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. |
Biochem/physiol Actions: | 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. |
Preparation Note: | Poly(ethylene glycol) dissolves in many organic solvents and is readily soluble in aromatic hydrocarbons. It also slightly dissolves in aliphatic hydrocarbons. |
