title: A new Cd-115 leads to In-115m radionuclide generator.
abstract: A new column-type Cd-115 leads to In- 115m generator has been developed by adsorbing CdI4(-2) on an anion-exchange resin and eluting the In-115m with 0.05 M HCl. The In-115m yield of the prototype column is 90% in a volume of 3 ml, with Cd-115 breakthrough of less than 3 X 10(-4)%. Over thirty generators with up to 40 mCi of activity have been produced using components of a commercial Mo-99 leads to Tc-99m generator system; they behaved like the prototype. In-115m oxine prepared from these generators has been used to label canine platelets and to image an induced canine thrombus in vivo.
