For these studies, either human serum or HEK293 exosomes concentrated from cell culture media using ExoQuick-TC were added to the antibody-coupled magnetic beads. After washing, exosomes were eluted and recovery estimated using a standard BCA protein assay.
Figure 1. CD63 and CD9, two exosome markers, are readily detected in samples purified using Exo-Flow Kits. Approximately 1 µg of protein was loaded per well on a 4-20% gradient protein PAGE. The proteins were separated and transferred to nitrocellulose membranes for Western blot analysis. The blots were probed with either with anti-CD63 or anti-CD9 antibodies to detect the exosome protein markers.
Figure 2. NanoSight analysis shows Exo-Flow IP Kits deliver good yields of particles whose sizes are consistent with exosomes.
