Binding and internalization into of CPV-VLPs into HeLa cells. HeLa cells incubated with Texas red-labeled transferrin (red) and CPV-VLPs were washed and fixed. Labeled antibodies (green) were used to detect the presence of CPV-VLPs in the cells by fluorescence confocal microscopy. (A) CPV-VLPs are seen as green areas in the cytoplasm, (B) shows localization of Texas Red-transferrin (red) and (C) depicts merged picture showing co-localization of CPV-VLPs and transferrin in yellow. Scale bar, 25 μm.
