FIGURE 1. Retention and release of 125I-, 211At-, 111In-, 205,6Bi-, and 203Pb-labeled T101 by PBMNC were determined. PBMNC (106) were incubated with 100 ng trace-labeled T101 at 4°C for 1 h and then washed, placed in fresh culture medium, and incubated at 37°C for 0, 1, 2, 4, and 8 h before quantifying amounts of cell-associated radioactivity and amount released into supernatant. Supernatant radioactivity was fractionated into methanol-precipitable noncatabolized component and methanol-soluble catabolized fraction. SD bars are plotted for replicates but are too small to be visualized for most time points.
