Fig. 4. (A) Structure of FC9-SL. (B) Laser scanning confocal microscopy of live MCF-7 cells incubated for 30 min (at 37 °C) in phenol red free DMEM in the presence of FC9-SL (15 μM) and the co-stains MemBrite 488 and Hoechst dyes. Blue channel: excitation at 405 nm, emission collected: 410–481 nm. Red channel: excitation at 594 nm, emission collected: 650–759 nm. Scale bar is 10 μm.
