Uptake of Cf-labeled Api137 (black), Api795 (blue), and Api794 (red) in HeLa cells determined by flow cytometry. (A) HeLa cells were incubated for the indicated times with Api137, Api795, or Api794 (40 μmol/L). (B) HeLa cells were treated for 45 min without (filled bars) or with dynasore (0.2 mmol/L, striped bars) before they were treated with a peptide (40 μmol/L) for 30 min. Cells not incubated with a peptide were used as controls (gray in histograms) without (C) or with dynasore (D).
