FLuoEVs: Purified EVs expressing EGFP (lyophilized)

FLuoEVs are stably-fluorescent extracellular vesicles expressing the fluorescent protein EGFP (green) and/or mCherry (red) as fusion proteins with tetraspanin markers CD9, CD81 and CD63. FLuoEVs are purified with a combination of tangential flow filtration (TFF) and size exclusion chromatography (SEC) from genetically engineered cells in order to express the fluorescent proteins as fusion protein with the tetraspanin CD9, CD63 or CD81. FLuoEVs demonstrated high stability of the fluorophores, they can be used for vitro tracking studies or as reference material for analyzers of nanoparticles or for assay calibration.
