Poly(ethylene glycol) may be used in the following studies: • For the modification of proteins to form the conjugates having increased circulating life and reduced immunogenicity and antigenicity.[3] • Preparation of hydrogels useful for the diffusion controlled delivery of proteins.[4] • Preparation of poly(ethylene glycol) dimethacrylate (PEGDM).[5]
General description
Poly(ethylene glycol) (PEG) is a non-toxic water-soluble polymer. PEG term is used for the polymer chains with molecular weights below 20 000, while poly(ethylene oxide) (PEO) refers to the higher molecular weight polymers.[4] PEG has various biomedical applications.[4] It forms complexes with α-cyclodextrins.[1] Engineering of PEG hydrogel particles by mesoporous silica (MS) templating method has been reported.[2]
