p80 expression and specific binding of TP-3 to OHS human osteosarcoma cells. (A) A flow cytometry histogram that demonstrates the binding of TP-3 to the p80 antigen (green curve), compared to the non-specific primary antibody rituximab (RTX; gray curve), OHS cells stained only with the secondary antibody (blue curve) or unstained control cells (black curve). (B) Specific binding (antigens per cell) and (C) percentage specific bound TP-3 (of total added) to OHS cells after 1 h incubation with 0.03–10 μg/ml of 212Pb-TCMC-TP-3.
