An IgG mouse monoclonal antibody (10F05) against polyethylene glycol has been generated. The antibody reacts with PEG regardless of the linker used for PEG attachment, and is able to recognize a PEGylated peptide in plasma at concentrations as low as 3 pg/mL. The antibody is readily purified in substantial quantities. The PEG IgG will find significant utility in the sensitive detection of PEG derivitives during the pharmacokinetic characterization of PEGylated compounds.
