Fig 5 — Liposomes containing SR with or without INF7 were incubated with CV1 cells for 1 hr, washed to remove un-endocytosed liposomes, and allowed to incubate without liposomes for an additional 2 hr. SR remains confined in endosomes without INF7 (-INF7), but after release into the cytosol by INF7, SR is rapidly transported from the cytosol into the extracellular volume (+INF7) leading to much dimmer fluorescence in cells incubated INF7-containing liposomes. See main text for more detailed mechanistic explanation.
