Fig. 5From: Intracellular trafficking and cellular uptake mechanism of PHBV nanoparticles for targeted delivery in epithelial cell linesCharacterization of the endocytosis mechanism using WGA marker. HeLa and SKOV-3 cells were incubated with PHBV-FITC for 5 min at 37 °C, in the presence of Alexa Fluor® 555-conjugated WGA. Later, cells were fixed and observed by fluorescence microscopy. Hoechst 33342 was used as a nuclear stain. Objective: ×60 magnification. Bar size 10 µmBack to article page
