Selective labeling of PSMA+ cells with the pre-formulated Cy5-streptavidin:biotin-PEG12-CTT54 complex. (A) LNCaP and (B) PC-3 cells treated with the pre-formulated complex (600 nM) for 1 h at 37 °C. (C) LNCaP cells pretreated (30 min) with nonfluorescent CTT54 (80 μM) prior to treatment with the pre-formulated complex. (D) LNCaP cells treated with Cy5-streptavidin only (600 nM). All cells were fixed and nuclei stained with Hoechst 33342 (blue). Cy5 fluorescence was assigned as pseudocolored red. Distance scale is 20 μm.
