Saturation binding assays performed on HER2-expressing BT474M1 breast carcinoma cells with 5F7 labeled using [131I]SGMIB, iso-[131I]SGMIB, [211At]SAGMB and iso-[211At]SAGMB. Cells (8 × 104) were incubated with increasing concentrations of the labeled sdAbs and specific cell-associated radioactivity determined as described in text. Plots were generated and Kd values calculated using GraphPad Prism software.
