Fluxion Biosciences and Swift Biosciences announce jointly developed next-generation sequencing workflow for somatic mutation detection from liquid biopsy samples

In advance of the 2015 American Society of Clinical Oncology Annual meeting, Fluxion Biosciences, Inc. and Swift Biosciences, Inc. announced a new workflow for oncology clinical research designed to detect somatic mutations from a routine blood draw. The jointly-developed workflow utilizes Fluxion’s IsoFlux™ System for circulating tumor cell (CTC) enrichment and Swift’s Accel-Amplicon™ technology for high sensitivity variant detection using low starting inputs.

Liquid biopsies represent a major breakthrough in the ability to detect molecular changes in tumor progression without the need for a tissue biopsy. They offer the potential to characterize cancer in real time using only a routine blood draw, enabling targeted therapies to be used simultaneously monitoring for response and resistance. Until recently, this approach has been limited by the available amount of tumor DNA that can be recovered from peripheral blood samples. The IsoFlux System enriches rare tumor cells circulating in the blood using a combination of epithelial and mesenchymal markers, and delivers them at high purity for molecular analysis. Swift’s Accel-Amplicon 56G Oncology Panel provides sensitive mutation detection across 56 cancer-related genes using very low starting DNA inputs from the IsoFlux System, making this combination of technologies especially appropriate for liquid biopsy samples.

“We’re pleased to be working with Swift on this application for translational oncology research,” said Michael Schwartz, VP Marketing at Fluxion. “We expect the combination of blood-based tumor DNA enrichment and broad tumor gene coverage to be put to good use by the types of institutions that are pursuing diagnostic strategies based on liquid biopsies.”

“This workflow is a wonderful example of how innovators can collaborate to produce advanced tools for oncology research,” noted David Olson, CEO at Swift Biosciences. “Fluxion's CTC enrichment is a great pairing with our 56G Oncology Panel, and we are pleased that our respective technologies can be used together to shine new light on cancer biology.”

The combined workflow begins with a standard blood draw and proceeds to CTC enrichment using epithelial and mesenchymal antibodies. The captured CTCs undergo DNA extraction and purification without the need for whole genome amplification. The genomic DNA then goes through target enrichment using the 56G Oncology Panel and library preparation for Illumina® sequencers. The resulting data utilizes a custom bioinformatics pipeline designed to identify low frequency variants from liquid biopsy samples. The complete workflow is described in an application note and the products involved are available from Fluxion and Swift. For more information, please visit: and

About Fluxion Biosciences
Fluxion Biosciences brings the power of cellular analysis to the benchtop with advanced tools to automate complex assays. The company’s IsoFlux System enables translational oncology research using a non-invasive liquid biopsy. This platform utilizes high-sensitivity circulating tumor cell (CTC) collection to facilitate broadbased genomic analysis using tools such as Next Generation Sequencing (NGS). This approach provides a more comprehensive look at the disease status, as compared to alternative approaches that only look at limited panels of known mutations. Fluxion’s other products, the BioFlux System and IonFlux System, have helped hundreds of research institutions and pharmaceutical companies around the world advance their cellular research and drug discovery.

About Swift Biosciences
Swift Biosciences is developing innovative and enabling technologies for genomics research. The company’s Accel-NGS product portfolio brings unique capabilities to improve the efficiency and quality of NGS sample preparation across multiple applications. The Accel-NGS library preparation kits offer superior sequence coverage metrics, even from challenging samples, and can generate PCR-free libraries for whole genome sequencing from as little as 10 ng of genomic input. The Accel-Amplicon products encompass multiple panels that include 56G, a stand-alone TP53 panel, and custom panels across multiple genomes. Swift Biosciences also offers kits for bisulfite-converted DNA for methylation sequencing and a product for singlestranded DNA, ideal for viral and phage metagenomes.
