Confocal laser scanning microscope images of HK-2 cells incubated with (A) HBc-183/CLT and (B) K3-HBc/CLT at different time points (0.5 and 1 h). Representative fluorescence images of nuclei counterstained with DAPI (blue) and HBc-183/CLT and K3-HBc/CLT labeled with Cy5.5 (red), Scale bars, 20 μm. C–E Flow cytometric analyses of HK-2 cells treated with FITC-labeled HBc-183/CLT or K3-HBc/CLT NCs for 0.5, 1, 2 and 4 h at 37 °C (n = 3) (***p < 0.001)
