Fig. 4From: Antiproliferative and Apoptosis Triggering Potential of Paclitaxel-Based Targeted-Lipid Nanoparticles with Enhanced Cellular Internalization by Transferrin Receptors—a Study in Leukemia CellsCellular uptake analysis of TPLN and PLN using confocal laser scanning microscope (CLSM) at 37 °C. Rhodamine B was used as a fluorescent dye and incubated for 3 h. The cellular uptake analysis was performed after incubating the nanoparticles for 3 h under 37 °C in incubator. Scale bar is 20 μmBack to article page
