The Cyclotron Group provides radionuclides to colleagues on and off campus. For the last decade, we have distributed radionuclides nationally. Copper-64, zirconium-89, yttrium-86, manganese-52g, and cobalt-55 are made and shipped Mondays for Tuesday delivery. Arsenic-72, bromine-76/77, manganese-52 and others are available on request. We are also members of the U.S. Department of Energy’s University Isotope Network (UIN); requests for Y-86, Br-77, and Mn-52 should be directed to contacts at isotopes.gov.

We also make the following standard PET isotopes for daily local use.

| 11C | 11CH3I/11CH3OTf | 20 min. | 10-25 |
| 13N | 13NH3 | 10 min. | – |
Finally, we can provide local collaborators unconventional isotopes upon request.

| 61Cu | 61CuCl2 | 3.3 hours | 1-2 (DOTA) |
| 55/58Co | 55/58CoCl2 | 17/70 hours | >1 (DOTA) |
| 80mBr | Na76/77Br | 4.4 hours | N.C.A. |

* The ISRS-defined quantity “apparent molar activity” is measured for many radiometals with a specified complexing ligand (e.g., DOTA or NOTA). The complexing ligand is shown parenthetically, and measurement are made using titrated solutions of the ligand and radio-TLC.
** EOB = End of Bombardment; EOS = End of Synthesis.
