Figure 2. CLSM images of ana-1 cells after incubation for 16 h with FITC-lysozyme (12 µg/mL) in the presence of pa-FOF (0-18 µg/mL). The lysosomes and nuclei were stained with Lyso-Tracker Red (red) and Hoechst 33342 (blue), respectively. Scale bar: 20 µm. CLSM: confocal laser scanning microscopy; FITC: fluorescein isothiocyanate; pa-FOF: polyanionic flexible organic framework.
