Fig. 1From: Scale down and optimized automated production of [68Ga]68Ga-DOTA-ECL1i PET tracer targeting CCR2 expressiona HPLC chromatogram of the radiodetector showing the eluate [68Ga]68GaCl3; b HPLC chromatogram of the radiodetector showing [68Ga]68Ga-DOTA-ECL1. The small minor peak just before [68Ga]68Ga-DOTA-ECL1 belongs to [68Ga]68Ga-DOTA-ECL1peak, infact in UV chromatogram there is only the peak of DOTA-ECL1i (Fig. 1c); c Radio-UV-HPLC chromatogram of DOTA-ECL1iBack to article page
