Biodistribution of radioactivity in AML-bearing SJL/J mice. Mice received 0.67 nmol of B10-30F11 conjugate trace-labeled with ¹²⁵I or ²¹¹At and were then euthanized at stated time points. Their organs were harvested, and radioactivity was measured for (A) ¹²⁵I at 8 (▪) and 24 hours (□) or for (B) ²¹¹At at 1 (□), 3 (▤), 7 (▪), and 24 (▨) hours after injection of radioactivity. Counts were decay-corrected and expressed as a percentage of the injected dose per gram of tissue (% ID/g). Sm Int, small intestine.
