Flow cytometry analysis using exosome markers CD81 and CD63 antibodies of serum exosomes coupled to 0.4 μm beads. Negative control (NC) corresponds to secondary conjugated antibody. a-c: the expression of exosome markers CD81 and CD63 in three donors'isolated exosomes of CNAG group; d-f: the expression of exosome markers CD81 and CD63 in three donors'isolated exosomes of CAG group
