Diastereomeric mixture [18F, natGa]rhPSMA-7 is composed of the four isomers [18F, natGa]rhPSMA-7.1 to -7.4, differing in the stereoconfiguration of diaminopropionic acid (D-/L-Dap) and DOTA-GA (R-/S-DOTAGA). The abundance of the diastereomers could be determined by HPLC-analysis of retained samples of previously produced batches of the diastereomeric mixture, [19F, natGa]rhPSMA-7 (n = 6)
