Fig. 1From: Novel insight into the lipid network of plasma extracellular vesicles reveal sex-based differences in the lipidomic profile of alcohol use disorder patientsCharacterization of plasma EVs. A Transmission electron microscopy image of human plasma EVs. B Analysis of the protein expression of EV markers (CD9, CD63, and CD81) in plasma EVs and astroglial cell lysates (positive control for calnexin expression). Calnexin expression was used to detect possible cytosolic protein contamination in EV samples. A representative immunoblot for each protein is shown. C Measurement of human EV size distribution (left) and concentration (right) by nanoparticle tracking analysisBack to article page
