PEG (polyethylene glycol) is a nontoxic, water-soluble, biocompatible polymer that has been approved by the FDA for human intravenous, oral and dermal applications. Attachment of PEG to proteins, peptides, liposomes, drugs, and nanoparticles can improve the pharmacokinetic properties and diminish the potential for immunogenicity. Even though PEG is generally considered safe in animals and humans, the slow clearance of large PEGs is still a great concern due to the potential adverse effects resulting from PEG accumulation in tissues following chronic administration.
To allow sensitive measurement of PEGylated compounds, Creative Diagnostics have produced a set of specific anti-PEG monoclonal antibodies. These antibodies have been validated to work in various types of immunoassays and can be supplied as high quality research tools to develop sensitive and specific assays.
