EVs are a small portion of particles in the serum, and the concentration is not changed with muscle atrophy in rats. A Western blot showing the separation of lipoprotein particles and CD63+ EVs in the serum using an iodixanol density gradient. B NTA quantification of the particle concentration from each fraction collected from the iodixanol density gradient shown in A (n = 3 WB and n = 3 HS). C Magnification of the NTA concentration data shown in B (n = 3 WB and n = 3 HS). D Summed particle concentration of fractions 1 through 4 of the density gradient. E Summed particle concentration of fractions 5 through 7 of the density gradient
