Abstract
A method of ameliorating degradation of radiolabeled peptides, especially radiolabeled proteins such as antibodies, by including povidone, also widely known as polyvinylpyrrolidone or PVP, as a radioprotectant in a composition containing a radiolabeled peptide is described. A radioprotectant composition and a stable peptide-radioisotope composition having povidone are also described. Ascorbic acid or other secondary stabilizers may also be added to the compositions to further enhance radioprotection.
