Radiolabeling and Quantitative In Vivo SPECT/CT Imaging Study of Liposomes Using the Novel Iminothiolane-^99mTc-Tricarbonyl Complex

Figure 4

Elution profile of the Tc-labeled liposomes on a PD-10 column. The first two fractions contain the labeled liposomes, while the free Tc-tricarbonyl is eluted with the total volume of the column.
