WebbEVs were isolated from human platelet-free plasma (PFP) of patients and healthy donors through size-exclusion chromatography (SEC) combined with ultrafiltration (UF). Then, EVs were characterized using transmission electron microscopy (TEM), imaging flow cytometry (IFC), and nanoparticle tracking analysis (NTA). WebbAutomated liquid chromatography under high pressure. – Size Exclusion: Sample is separated by size using a special solid phase. Larger species elute first. – Ion Exchange: Chemical of interest stays with the oppositely charged solid phase, a buffer is used to change the chemical’s charge and allow it to elute. – Affinity
