Abstract

<p>Figure S2: A, MALDI-TOF Mass spectroscopy results show 8.7 equivalents of DOTA molecules on the YS5 antibody. The number of DOTA were calculated by dividing the difference of m/z between YS5 and DOTA-YS5 by the molecular weight of DOTA. B, Size-exclusion chromatogram shows no aggregation of the [225Ac]DOTA-YS5 after the radiolabeling steps. C, Stability of the [225Ac]DOTA-YS5 tested in saline and human serum for 14 days. D, Comparison of the binding assay results after attaining secular equilibrium vs without secular equilibrium. No significant difference was observed for these two assays (n=4).
