MOESM3 of Development of elastin-like polypeptide for targeted specific gene delivery in vivo

Additional file 3: Figure S3. Cell binding of ELP variants. MDA MB231 cells were incubated with Alexa Fluor 488 labeled ELPs for 1 h at 4 °C. After staining nuclei and membranes with Hoechst 33342 or WGA-Alexa 594, cell binding activities were determined by confocal microscopy. Scale bar, 20 µm.
