Overview
Easily track exosomes with a CD81-RFP fusion
Monitor exosome dynamics with the pCT-CD81-RFP (pCMV) Exosome Cyto-Tracer (also available as a CD81-GFP fusion, pCT-CD81-GFP). Provided as either lentivector or pre-packaged virus, this Cyto-Tracer fuses RFP to the tetraspanin CD81, which then gets packaged into exosomes produced by the transfected cells. Great for creating stable cell lines that produce RFP-labeled exosomes as well as labeling exosomes from primary cells, tumor cells, stem cells, and more.- Stable lentivector-based system
