Accumulated confocal images for intracellular trafficking of the anionic polyelectrolyte/LYZ complexes (WR 1) and LYZ (25 ìg/mL) in MCF7 cells. The MCF7 cells (1×105 cells) for imaging uptake of the polyanion/LYZ complexes and free LYZ were seeded in each well of a 6-well plate and were exposed to free LYZ and the complexes for 4 hr. Free LYZ was labeled with RITC (red). Acidic compartments and nuclei were stained with LysoTracker® Green (green) and Hoechst 33342 (blue), respectively.
