Fig. 1From: Circulating miRNAs in extracellular vesicles related to treatment response in patients with idiopathic membranous nephropathyIsolated extracellular vesicles (EVs) from the serum samples of patients. A Diagram of the observed peaks of nanoparticles in three patient serum EVs by dynamic light scattering (DLS) using Nano-ZS Zetasizer. B Transmission electron microscopy showing membranous vesicles of purified serum EVs. Scale bar, 200 nm. C Western blot analysis of EVs using positive marker as CD9 and negative marker as GM-130. D Cluster of differentiation 63 (CD63) expression levels in the serum-derived EVs as determined by the enzyme-linked immunosorbent assay (ELISA). Bars represent mean ± SD of three EVs from different samplesBack to article page
