Characterization of exosomes from breast cancer cell lines. Exosomes were isolated from the conditioned media of MCF10A, MCF7, and MDA-MB-231 cells. a Nanoparticle tracking analysis of 50X diluted MCF10A, MCF7 and MDA-MB-231 exosomes. b MCF7 and MDA-MB-231 exosomes were visualized by electron microscopy (×30,000). c MCF7 and MDA-MB-231 exosomes were immunogold-labeled and visualized by electron microscopy of human CD63-gold particles (10 nM gold) (right × 40,000; left × 100,000). d Western blot of CD63 (30–60 kDa) under non-reducing conditions
