Radioidohippuric acid ester, a conjugate thereof, and methods of making the same

摘要

The novel N-hydroxysuccinimide ester of iodohippuric acid (IH-OSU), capable of forming a stable conjugate with a protein. The iodohippuric acid is preferably orthoiodohippuric acid (OIH) and radiolabeled. A protein compound useful as a radiolable comprises a stable conjugate of a protein and the N-hydroxysuccinimide ester of radiolabeled iodohippuric acid.
