{{DISPLAYTITLE:Technetium (99mTc) nofetumomab merpentan}} Technetium (99mTc) nofetumomab merpentan (trade name Verluma) is a mouse monoclonal antibody derivative used in the diagnosis of lung cancer, gastrointestinal, breast, ovary, pancreas, kidney, cervix, and bladder carcinoma. The antibody part, nofetumomab, is attached to the chelator merpentan, which links it to the radioisotope technetium-99m (99mTc). Nofetumomab Nofetumomab is an antibody fragment that recognises the pancarcinoma glycoprotein antigen EpCAM. and/or CD20/MS4A1 It is the Fab part of murine MAb NR-LU-10. Merpentan The chelator part : merpentan is a phenthioate ligand, 2,3,5,6-tetrafluorophenyl-4,5-bis-5-[1-ethoxyethyl]-thioacetoamidopentanoate.
