Time-dependent uptake of the pre-formulated Cy5-streptavidin:biotin-PEG12-CTT54 complex in PSMA+ cells. Live LNCaP cells were incubated with pre-formulated complex (600 nM) for 5 (A), 10 (B), 15 (C), 30 (D), and 60 (E) min at 37 °C. All cells were fixed and nuclei stained with Hoechst 33342 (blue). Cy5 fluorescence was assigned as pseudocolored red. Distance scale is 20 μm.
