A549 cells were infected with A/PR/8/34 (H1N1) (MOI = 0.1) and treated with LH-C (2 mg/mL) or vehicle. After 6 and 8 h post infection, the cells were fixed for 30 min at 4 °C. Cell nuclei were stained with DAPI (blue) and viewed using a fluorescence microscope (Magnification 400×)Back to article page
