MOESM6 of Development of elastin-like polypeptide for targeted specific gene delivery in vivo

Additional file 6: Figure S6. Cellular uptake of ELP variants. 4T1 cells were incubated with Alexa Fluor 488 labeled ELP variants for 1 h at 37 °C. After staining nuclei and membranes with Hoechst 33342 or WGA-Alexa 594, cellular uptakes were assessed by confocal microscopy. Scale bar, 20 µm.
