Application data by workflow step

Exosome isolation

Exosomes belong the to group of extracellular vesicles (EV) and play a key role in cellular functions. Consequently, they are of great interest in basic research as well as in future diagnostic applications or clinical settings. We offer a reliable isolation method that safes time, capital equipment, and high starting volumes (50–100 mL) – a true alternative for conventional ultracentrifugation.

Isolation of EVs using MACS® Technology

Using our Exosome Isolation Kit, enrichment of EVs has never been easier.

  • Selection of EVs according to surface markers i.e. CD9, CD63, or CD81  

  • Low starting volume of samples (0.5 to 2 mL)

  • Isolation from multiple sample types e.g. cell culture supernatant, urine, plasma, serum, ascites etc.

Separation of EV subpopulations

Subpopulations of EVs can be separated using superparamagnetic MACS® MicroBeads. For example, NK cell EVs and platelet EVs can be separated using CD81+ and CD9MicroBeads.

Exosome analysis

For further downstream analysis of exosomes we have established the MACSPlex Exosome Assay. This multiplex bead-based assay consists of capture and detection antibodies to analyze the composition of exosome surface proteins in a given sample by flow cytometry.

Advantages of the MACSPlex Exosome Assay

  • Comprehensive – Fast and easy screening of 39 surface markers on EVs

  • Flexible – Additional antibodies can be added for multi-parameter analysis

  • Express Mode – Automated acquisition and analysis in combination with the Express Mode on the MACSQuant® Flow Cytometers.

Discrimination of EVs by differing tumor markers

EVs isolated from cancer cell lines can be discriminated by differing markers from tumor entities. EVs from melanoma cell line for instance show different surface markers then EVs from colon cancer cells as demonstrated by binding to the respective MACSPlex Exosome capture beads.
