Fig. 1From: Validation of a size exclusion method for concomitant purification and formulation of peptide radiopharmaceuticals(A) Retention capacity of the G10 size exclusion cartridge for the free 68Ga, 64Cu and 99mTc-radionuclide salts as present in the radiolabeling mixture. Saline (0.9% NaCl) was used for elution. (B) Exemplary correlation between elution volume and pH of the final product [68Ga]Ga-PSMA-617 in labeling buffer (1 M NaOAc, pH 4.5)Back to article page
