商品信息

.img-style{heigth:450px;width:450px;}
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

Ideal for co-localization studies

Monitor exosome dynamics and functional studies in real time

Label exosomes from primary cells, tumor cells, stem cells, and more


Choose the exosome quantitation method that’s best for your studies
