Fig. 4. Time-lapse confocal microscopy in live cells. The wild type (wt) and overexpressing hCB2R- and hCB1R-CHO cells were co-stained with probes 12, 14–16 and 18 and Hoechst 33342 (blue, nucleus counterstain). The images were recorded 10 min after probe incubation. Images are representative of two independent experiments. Scale bars, 10 μm.
