Figure 3.
Dose-dependent cell labeling with Cy5.5-CTT-54.2. (A-E) Live LNCaP cells were treated with Cy5.5-CTT-54.2 at various concentrations (10, 5, 2.5, 1.5 and 0.625 μM) for 2 h at 37 °C. All cells were fixed and nuclei stained with Hoechst 33342 (blue). Cy5.5 fluorescence was assigned as pseudocolored red. Distance scale is 20 μm.
