Description

pCT-CD9-GFP (pCMV, Exosome/Secretory, CD9 Tetraspanin Tag). Cat# CYTO122-PA. Supplier: SBI System Biosciences

Label exosomes with GFP by expressing the pCT-CD9-GFP Cyto-Tracer in the parent cells. Great for tracking exosomes and monitoring cargo delivery.
  • 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

Overview

Easily track exosomes with a CD9-GFP fusion
Monitor exosome dynamics with the pCT-CD9-GFP (pCMV) Exosome Cyto-Tracer (also available as a CD9-RFP fusion, pCT-CD9-RFP). Provided as either lentivector or pre-packaged virus, this Cyto-Tracer fuses GFP to the tetraspanin CD9, which then gets packaged into exosomes produced by the transfected cells. Great for creating stable cell lines that produce GFP-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

(B) Representative images from confocal time-lapse microscopy of mouse ECs (ACTB-DsRed) (EC; red) co-cultured with H9C2-CD63-GFP cells (green), previously cultured for 24 h in +/-St medium. Exosome transfer from H9C2 CMs to EC can be observed (S1 and S2 Movies, below). White arrows show CD63-GFP structures inside ECs (C) Representative immunostaining of H9C2-CD63-GFP and HUVEC co-cultures; anti-GFP (green) and anti-CD31 (red). The images illustrate GFP fluorescence from CD63-GFP exosomes in CD31-positive cells (red) after 24 h incubation in +/-St medium. White arrows show CD63-GFP structures inside ECs.
