Which isotopes can I use to radiolabel IgG after chelation using GlyCLICK?

The GlyCLICK technology can be used to conjugate IgG with Desferrioxamine (DFO) using the GlyCLICK DFO kit. The DFO is a chelating agent for radiolabeling with the radioisotope Zirconium-89 (89Zr) for PET-imaging. The Azide Activation kit can be used to conjugate a chelator of choice if it is alkyne-modified (carrying for example DIBO, DBCO or BCN) to be compatible with the click chemistry.
