In extracellular vesicle (EV) research, the quality of your isolation method can make or break your experiments. For over a decade, researchers have turned to Exo-spin for reliable, high-purity EV isolation without the complexities of traditional ultracentrifugation. Here’s why Exo-spin has become a trusted choice in hundreds of published studies.

The Challenge of EV Isolation

Isolating extracellular vesicles from biological samples has traditionally been a bottleneck in research workflows. Ultracentrifugation requires specialized equipment, lengthy protocols, and technical expertise. Other methods often compromise on either purity or yield, leaving researchers to choose between quality and practicality.

Exo-spin™: Simplicity and Performance

Exo-spin™ leverages the proven principles of size exclusion chromatography (SEC) to separate EVs based on particle size. The technology is elegantly simple: columns packed with specialized polymeric beads containing nano-scale pores act as molecular sieves. Larger EVs (30-250nm) pass through the gaps between beads and elute first, while smaller contaminants like free proteins become trapped in the pores and are left behind.

Key Benefits of Exo-spin™ That Matter

• No Ultracentrifugation Required Perhaps the most significant advantage of Exo-spin is eliminating the need for ultracentrifugation. This means no specialized equipment, no overnight runs, and no bottlenecks when multiple researchers need access to instruments. Your lab can conduct EV isolation with standard benchtop centrifuges.
• Outstanding Purity Levels Exo-spin™ delivers EVs with minimal protein and ribosomal RNA contamination. Depending on the column format, you can achieve purity levels ranging from 99.0% to 99.8%, ensuring that downstream analyses reflect true EV characteristics rather than contaminant signals.
• Excellent Yields High purity doesn’t come at the expense of yield. Exo-spin™ provides excellent recovery of intact EVs, giving you sufficient material for comprehensive downstream applications including proteomics, RNA analysis, and functional studies.
• Simple, Reproducible Protocols The workflow is straightforward: spin your sample to remove cells, equilibrate the column, add your sample, and collect purified EVs. The consistency of SEC technology means reproducible results every time, reducing experimental variability and failed preps.
• Preserve EV Integrity Unlike harsh isolation methods, Exo-spin’s gentle size-based separation maintains EV structural integrity, making it ideal for functional studies where EV activity matters.
• Flexible Formats for Every Need Whether you’re processing 100 µl of precious plasma or liters of cell culture media, there’s an Exo-spin format for your application:
  • Exo-spin™ mini: Perfect for small volumes with rapid protocols
  • Exo-spin™ midi: Handles larger volumes up to 1 ml directly
  • Exo-spin™ mini HD: Extended bed length for maximum purity (99.8%)
  • Exo-spin™ 96: High-throughput 96-well format for screening applications
    For dilute samples like cell culture media or urine, Exo-spin can be combined with precipitation buffer to concentrate EVs before purification.
• Cost-Effective Performance When compared to ultracentrifugation, tangential flow filtration, or affinity capture methods, Exo-spin offers excellent value. The columns can be reused up to five times, either for iterative loading of large samples or for multiple different samples, further improving cost-effectiveness.
• High Throughput Capability With simple protocols that don’t require lengthy centrifugation runs, you can process multiple samples in parallel, dramatically increasing your lab’s throughput.
