Fig. 5From: Antiproliferative and Apoptosis Triggering Potential of Paclitaxel-Based Targeted-Lipid Nanoparticles with Enhanced Cellular Internalization by Transferrin Receptors—a Study in Leukemia CellsCytotoxicity analysis of free drug and drug-loaded nanoparticle by MTT assay. After treating the cells with different concentration of drugs and incubated for 24 h, cells were analyzed by MTT assay and using a plate reader. The measurement was performed n = 6. *p < 0.05 is the statistical difference between TPLN and PTXBack to article page
