Abstract
A radiochemical synthesis of [18F]DK222, a peptide binder of programmed death ligand 1 protein, suitable for human PET studies is described, and results from validation productions are presented. The high specific activity radiotracer product is prepared as a sterile, apyrogenic solution that conforms to current Good Manufacturing Practice (cGMP) requirements. In addition, the production is extended to use a commercial synthesizer platform (General Electric FASTlab 2).

PEG36-Nle(O-Bzl)-Met(O)2-Oic-Abu-ACC was designed in house and synthesized by CPC Scientific Inc (San Jose, CA, Fig. S1). Amino-PEG36-acid (CAS: 196936-04-6) and 2-(7-amino-2-oxochromen-4-yl)acetamide (CAS:296236-23-2) were used for the synthesis. The synthesized sensor was resuspended in high-performance liquid chromatography (HPLC)-grade water with a concentration of 200 µM.
