PRESS RELEASE: System Biosciences (SBI), a leading provider of exosome research tools and services,

announced today that QIAGEN, a leading global provider of Sample to Insights solutions for molecular diagnostics and life sciences, has signed a non-exclusive, worldwide license for SBI's patented ExoQuick® technology for research use. QIAGEN intends to use the ExoQuick technology in precipitation-based miRCURY™ products complementing its leading portfolio of spin column-based exoEasy and exoRNeasy product lines.

"QIAGEN's license demonstrates the value of ExoQuick technology for high-throughput, scalable isolation of exosomes from a range of biofluid samples," said Jake Lesnik, Vice President of Commercial Development at SBI. "The license agreement also demonstrates SBI’s commitment to protecting its proprietary ExoQuick technology, which is used by thousands of researchers globally for fast and efficient exosome isolation."

Once thought to be little more than a way for cells to offload waste, exosomes (small extracellular vesicles ranging in size from 30 – 200 nm) are a rapidly expanding area of study in basic research, biomarker discovery and therapeutic delivery. These extracellular vesicles function as signal carriers and tissue re-shapers through their cargo of RNA, proteins, and lipids, and are involved in a wide range of healthy and pathogenic processes including cancer, inflammation, immunity, CNS function, and cardiac cell function. Exosomes are found in a wide range of biofluids, including serum, plasma, ascites fluid, urine, saliva and tissue culture media, and are considered a rich source of material for biomarker discovery, including for liquid biopsy diagnostic development.

In 2009, the team at SBI recognized the great potential of exosomes and developed the first commercial exosome isolation kit, ExoQuick. In the intervening years, the ExoQuick family of products has gone on to be cited in over 600 peer-reviewed scientific publications, making it the most published exosome isolation reagent in the world. SBI remains focused on refining and enhancing its exosome isolation technology to continue to support the growing exosome research community.
