Uptake of [¹⁸F]FAZA into Caki-1 (renal cell carcinoma) and MCF-7 cells (human breast cancer cell line). Cell uptake was normalized to percent radioactivity per milligram protein, and data are shown as mean ± SEM from n analyzed cell culture dishes from x number of experiments. Cell uptake was measured under normoxic and hypoxic conditions and in the presence and absence of 3 µM sunitinib.
