Company:

Qiagen

Product Name:

miRCURY Exosome Cell/Urine/CSF Kit

Catalog Number:

76743

The miRCURY exosome kit was used to isolate EVs from conditioned media of 2D stem cell and cardiac cell cultures. Pelleted EVs were analyzed via nanoparticle tracking, which suggested the successful isolation of particles in the 100-200nm range.

Experimental Design and Results Summary

Application

Isolation of exosomes/EVs from conditioned cell culture media

Starting Material

Conditioned media from stem cells, cardiac cells

Tips

Starting media should be serum free, or use exosome depleted serum.

Results Summary

Exosomes and extracellular vesicles (EVs) were successfully precipitated from endothelial cell culture conditioned media using the Qiagen miRCURY kit. Isolates were analyzed using nanoparticle tracking analysis, which revealed a mean size of 159 nm and a concentration of 1.67x10^8 particles/ml (see attached image of size distribution).

Summary

The Good

Fast and easy to use, high yield of exosomes/extracellular vesicles.

The Bad

Higher cost than similar/simpler PEG buffers for isolation, requires optimization with cell culture media (works best without serum or with exosome depleted serum), non-specific isolation of all extracellular vesicles and non-exosomal particulates/aggregates in culture media.

The Bottom Line

This product produces excellent results for fast, easy, and high yield isolation of exosomes and extracellular vesicles without requirements for special equipment like an ultracentrifuge. The trade off compare to other isolation techniques is that the kit will non-specifically isolate non-exosomal aggregates leftover in the media even after pelleting larger cell debris. This kit is a great place to start when initiating and optimizing new experiments involving exosome and EV isolation.
