Abstract

Single-cell analysis can help to resolve the heterogeneous and complex biogenesis of extracellular vesicles (EVs), thereby improving our understanding of EVs’ role in signalling and cell-cell communication. Here, we introduce a method to detect up to five membrane proteins in EVs secreted from single cells. Two microwell arrays, one for single-cell trapping and another one for capturing fluorescently barcoded beads pre-functionalized with EV-capture antibodies, are aligned during incubation. Then, membrane proteins of bead-bound EVs are analysed by immunostaining for four breast-derived cell lines.
