Cellular uptake efficiency of BT474 and MCF7 cells determined by flow cytometry. BT474 and MCF7 cells were treated with medium, double fluorescence labeled eTmab-PPLNs or Tmab + eTmab-PPLNs. Tmab + eTmab-PPLNs represented free Tmab preincubation plus fluorescence labeled eTmab-PPLNs. eTmab-PPLNs indicates electrostatically conjugated trastuzumab-bearing poly (d, l-lactide-co-glycolide)/polyethylenimine/lipid nanoparticles; PPLNs, poly (d, l-lactide-co-glycolide)/polyethylenimine/lipid nanoparticles; Tmab, trastuzumab.
