Assays of epitopes on the isolated EVs. The EVs were trapped on a magnetic bead covalently linked to anti-CD63 and then assayed for additional epitopes by flow cytometry (35). Data were gated for single beads. (Left) Detection of CD63 as a function of the concentration of protein added. In the remaining panels, EVs were positive for CD63 and CD81 but not for CD9.
