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

WebbSize exclusion chromatography (SEC) is a type of liquid chromatography used for the separation and purification of molecules based on their size or molecular weight. It is a non-destructive method that separates molecules in solution based on their ability to enter and interact with pores in a stationary phase of beads or gel. Reversed-phase chromatography (RPC) is any liquid chromatography procedure in which the mobile phase is significantly more polar than the stationary phase. It is so named because in normal-phase liquid chromatography, the mobile phase is significantly less polar than the stationary phase. Hydrophobic molecules in the mobile phase tend to adsorb to the relatively hydrophobic stationary phase. Hydrophilic molecules in the mobile phase will tend to elute first. …
