Differential uptake and excretion pattern: relative percentage difference between the abundance of [¹⁸F, ^natGa]rhPSMA-7.1 to -7.4 in blood, liver, kidney, urine and tumor of male LNCaP tumor-bearing SCID mice (30 min p.i.) compared with the respective abundance found in the quality control of diastereomeric mixture [¹⁸F, ^natGa]rhPSMA-7. n = 4 in four independent experiment; the liver from the first experiment was not analyzed (see also Additional file 1: Fig. 9)
