Patent ID: 8575100

Claim:
A somatostatin receptor (sst) binding molecule comprising: a peptidic ligand selected from the group consisting of octreotide and octreotate; a sugar selected from the group consisting of glucose, galactose, maltose, mannose, maltotriose, and lactose; and a multidentate chelating group selected from the group consisting of histidine, picolylamine diacetic acid, hydroxyl nicotine amide (HYNIC) and mercaptoacetyl-glycyl-glycine (MAG-3) that complexes a radioisotope selected from Tc and Re, wherein (i) the chelating group is bound to the N-terminal of the ligand and the sugar is bound to the chelating group or (ii) the sugar is bound to the N-terminal of the ligand and the chelating group is bound to the sugar.
