Figure Lengend Snippet: (A) Western blot analysis of hEphA2. Lysates of PC3 and HeLa cells (8 × 10 5 ) were separated by SDS-PAGE and transferred to nylon membranes. Membranes were stained with rabbit anti-hEphA2 or β-actin antibodies. (B) Flow cytometric analysis of cells. Cells (5 × 10 5 ) were stained with mouse anti-hEphA2 and Alexa 488-conjugated anti-mouse IgG antibodies (anti-hEphA2), and fluorescence was measured by flow cytometry. Unstained cells or cells stained with Alexa 488-conjugated anti-mouse IgG antibody (2 nd Ab) alone were used as controls.

Article Snippet: Cells (1 × 10 4 ) were cultured on cover glasses on 6-well plates for 24 h. To detect bound E1-Rluc8, cells were incubated with 25.5 nM E1-Rluc8 and rabbit anti-hEphA2 antibody (1:10000 dilution, Santa Cruz Biotechnology), in 3 mL of culture medium containing 3% FBS at 37°C for 2 h. After the plates were washed with 1% BSA in PBS-T, they were incubated in FITC-conjugated anti-6×His (1:1000 dilution) and Alexa 555-conjugated anti-rabbit IgG antibodies (1:1000 dilution) for 2 h in the dark at room temperature (RT).

Figure Lengend Snippet: (A) Flow cytometric analysis of cells treated with E1-Rluc8 and E1-EGFP. PC3 and HeLa cells (5 × 10 5 ) detached from culture plates were treated with E1-Rluc8 and E1-EGFP. The cells treated with E1-Rluc8 were stained with FITC-conjugated mouse anti-6×His antibody. Unstained cells or cells stained with FITC-conjugated secondary antibody (2 nd Ab) alone were used as controls. (B) Fluorescence microscopy images of the cells. PC3 and HeLa cells were stained with mouse anti-hEphA2 antibody and E1-Rluc8, and then detected with Alexa 555-conjugated anti-mouse IgG (red) and FITC-conjugated anti-6×His antibodies (green). Cell nuclei were stained with DAPI (blue). Scale bar, 10 μm. (C) Fluorescence microscopy images of xenograft tumor tissues. PC3 tumor tissues from transplanted nude mice were stained with the antibody combinations used in (B). Scale bar, 10 μm.

Figure Lengend Snippet: (A) Measurement of luminescence in mice injected with different concentrations of E1-Rluc8. PC3 and HeLa cells were transplanted into 6-week-old Balb/c nude mice via subcutaneous injection (n = 3). After tumor formation, the indicated amounts of E1-Rluc8 and coelenterazine were intravenously injected via the tail vein, and luminescence images were acquired at the indicated times with the NightOWL in vivo imaging system (left). The luminescence intensities measured in tumor areas at 6 h were graphed (right). (B) Luminescence maintenance in mice injected with E1-Rluc8 for 24 h. E1-Rluc8 (60 μg) and coelenterazine were intravenously injected via the tail vein into PC3 tumor mice (n = 5), and luminescence images were obtained at the indicated times (left). The luminescence intensities in tumor tissues were measured with the NightOWL in vivo imaging system and graphed (right). (C) Detection of the remaining E1-Rluc8 in PC3 tumor tissues. Tumor tissues were collected at the indicated times from mice injected with E1-Rluc8 and stained with FITC-conjugated anti-6×His antibodies (green). hEphA2 was stained with mouse anti-hEphA2 antibody and Alexa 555-conjugated anti-mouse IgG (red). Cell nuclei were stained with DAPI (blue). Scale bar, 10 μm.
