(A) Fluorescent image of ExoFlo™ that was triple stained with antibodies against tetraspanin proteins reported in the literature to be enriched in exosomes using the NanoView Biosciences NanoView system. Red fluorescence, CD63; blue fluorescence, CD9; green fluorescence, CD81. (B) Semiquantification analysis of ExoFlo nanoparticles captured on different Nanoview antibody capture arrays. Data demonstrate an exosome population highly enriched for CD63 expression is the dominant EV population. EV, extracellular vesicle.
