Fig. 3From: Precise visualization and ROS-dependent photodynamic therapy of colorectal cancer with a novel mitochondrial viscosity photosensitive fluorescent probeViscosity detection in HCT-116 cells with HTI (10 μM) under different stimulants. A CLSM images of cells incubated with HTI for 30 min in different viscosity stimulants, monensin and nystatin, separately. Blue channel for Hoechst-33342: λex = 405 nm, λem = 455 ± 20 nm. Red channel for HTI: λex = 570 nm, λem = 610 ± 20 nm. Scale bar, 10 μm. B The plots of relative fluorescence intensities of the blank group vs the monensin group vs the nystatin group. Data are presented as mean ± s.d. (n = 3). **** p < 0.0001Back to article page
