Abstract

The PET tracer [18 F]F-AraG, an arabinosyl guanine analog, has shown promise for visualizing activated T cells in multiple diseases. Herein, a practitioner's protocol is described, in which the PET tracer is prepared using minimal equipment and manual actions, making it widely accessible for preclinical applications.

Keywords: AraG; SPE purification, T cell imaging; [18F]F-AraG; nucleophilic fluorination; nucleophilic substitution; practitioner's protocol.
