Validation of PBA on exosomes using antibodies to CD9 and CD63. a Separate incubation: exosomes isolated from the K562 cell line were incubated with two distinct sets of PBA probes separately before they were pooled for PBA. b Mixed incubation: exosomes were incubated with four different PBA probes before PBA was performed
