Polypeptides such as enzymes and insulin are coupled to polyethylene glycol or polypropropylene glycol having a molecular weight of 500 to 20,000 daltons to provide a physiologically active non-immunogenic water soluble polypeptide composition. The polyethylene glycol or polypropylene glycol protect the polypeptide from loss of activity and the composition can be injected into the mammalian circulatory system with substantially no immunogenic response.
A physiologically active, substantially non-immunogenic water soluble polypeptide composition comprising, a physiologically active polypeptide coupled with a coupling agent to at least one substantially linear polymer having a molecular weight of between about 500 to about 20,000 daltons selected fr
A physiologically active, substantially non-immunogenic water soluble polypeptide composition comprising, a physiologically active polypeptide coupled with a coupling agent to at least one substantially linear polymer having a molecular weight of between about 500 to about 20,000 daltons selected from the group consisting of polyethylene glycol and polypropropylene glycol wherein the polymer is unsubstituted or substituted by alkoxy or alkyl groups, said alkoxy or alkyl group possessing less than 5 carbon atoms.
