New Chelator for Radiolabelling

In a joint research effort supported by the Swiss National Science Foundation, the groups of Prof. Gilles Gasser (Chimie ParisTech) and Prof. Thomas Mindt (LBIAD) have developed a new chelator for the radiolabelling of antibodies and other molecules with the PET radiometal zirconium-89.[1]

The new chelator, termed DFO*, provides 89Zr-complexes that are extraordinarily stable in vivo.[2] The compound has now become commercially available from the German company ABX.
