From: Uptake of ricinB-quantum dot nanoparticles by a macropinocytosis-like mechanism
Inhibition of ricinB:QDot endocytosis upon treatment of cells with EIPA, an inhibitor of macropinocytosis. RicinB: QDs (red) were pre-bound to HeLa cells at 4°C, and then internalized in the presence of alexa594 dextran (green) for 30 min (panel A,B) and 90 min (panel C,D), respectively. The cells were fixed and stained with lysosomal antibody CD63 and its corresponding secondary antibody-Cy2 (blue). The cell nuclei were stained with Hoechst33342 (white).
