Fig. 3From: PLGA-PEG Nanoparticles Coated with Anti-CD45RO and Loaded with HDAC Plus Protease Inhibitors Activate Latent HIV and Inhibit Viral SpreadCellular uptake analysis of coumarin-6-labelled NPs. a Confocal images of H9 cells. Cells were treated with scFv CD45RO-coumarin-6 NPs or coumarin-6 NPs and incubated for 12 h. Nuclei were stained with Hoechst 33342 (blue) and coumarin-6 (green) (×400). b Flow cytometry analysis of cellular uptake of scFv CD45RO-coumarin-6 NPs in a time-dependent manner.
