In flow cytometry analysis, molecules on cells can be detected by labeling with antibodies or other reagents. However, extracellular vesicles (EVs) released by cells are of a small particle size, making it difficult to detect molecules on EVs using conventional flow cytometry. Here, we describe a method for isolating EVs secreted by cells and report a flow cytometry analysis for gangliosides on EVs. By using Tim4-conjugated beads, which bind specifically to EVs, molecules expressed on EVs can be easily detected even with flow cytometry.
