MedKoo Cat#: 125509 | Name: RM-2 Ga-68

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Gallium Ga 68-labeled RM2 is a radioconjugate containing a synthetic bombesin receptor antagonist targeting the gastrin-releasing peptide receptor (GRPR), that is linked by the macrocyclic chelator 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) to the radionuclide gallium (Ga) 68, with potential use in diagnostic imaging using positron emission tomography/computed tomography (PET/CT).
