Application

Poly(ethylene glycol) was used as hydrophilic carriers for characterizing the sirolimus solid dispersion nanoparticles.

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.
