Abstract
The present invention relates to novel compositions comprising high levels of copper-64 (e.g., high radionuclidic purity, high activity, and/or high specific activity), and processes for preparing said compositions. The compositions may comprise from about 2 Ci to about 120 Ci, about 15 Ci to about 120 Ci, about 20 Ci to about 120 Ci, about 30 Ci to about 120 Ci, about 40 Ci to about 110 Ci, or about 50 Ci to about 120 Ci of isolated copper-64 and/or have specific activities of about 10 mCi to about 3850 mCi copper-64 per microgram of copper. The processes for preparing said compositions may comprise bombarding a nickel-64 target with a low-medium energy, high current proton beam, and purifying the copper-64 from other metals by a process comprising ion exchange chromatography and/or a process comprising a combination of extraction chromatography and ion exchange chromatography.
