Optimisation of the Synthesis and Cell Labelling Conditions for [⁸⁹Zr]Zr-oxine and [⁸⁹Zr]Zr-DFO-NCS: a Direct In Vitro Comparison in Cell Types with Distinct Therapeutic Applications.

ABSTRACT:

Background

There is a need to better characterise cell-based therapies in preclinical models to help facilitate their translation to humans. Long-term high-resolution tracking of the cells in vivo is often impossible due to unreliable methods. Radiolabelling of cells has the advantage of being able to reveal cellular kinetics in vivo over time. This study aimed to optimise the synthesis of the radiotracers [⁸⁹Zr]Zr-oxine (8-hydroxyquinoline) and [⁸⁹Zr]Zr-DFO-NCS (p-SCN-Bn-Deferoxamine) and to perform a direct comparison of the cell labelling efficiency using these radiotracers.

Procedures

Several parameters, such as buffers, pH, labelling time and temperature, were investigated to optimise the synthesis of [⁸⁹Zr]Zr-oxine and [⁸⁹Zr]
