FLuoEVs: Purified EVs expressing BFP (lyophilized)
FLUO-EVs are stably-fluorescent Extracellular vesicles expressing the fluorescent protein BFP (blue) as fusion protein with tetraspanin CD81. FLUO-EVs are purified in 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 CD81. FLUO-EVs 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.
Characteristics: Particle size distribution 50 – 140 nm, lyophilized, storage at 4-8 °C.
Applications: Positive control for EV analyzers (NTA, flow Cytometers, fluorescence microscopy), cell spike-in and in vitro tracking, EV uptake monitoring, assay and instrument calibration.
