Highly accurate sequencing for liquid biopsy
Unlock exciting new possibilities in liquid biopsy research with PacBio short-read sequencing-by-binding (SBB) technology. SBB delivers incredible Q40+ accuracy – far exceeding the capabilities of traditional short-read platforms. This means less noise and more sensitivity for detecting even the rarest variants. Paired with a lower coverage requirement and superior performance in low complexity regions, PacBio SBB technology provides a more comprehensive solution enabling cancer researchers to see the unseen and drive progress in liquid biopsy like never before.

Get superior ctDNA detection by reducing noise due to sequencing errors
Reduced sequencing
Q40+ accuracy provides high quality mutation detection at lower read depths than SBS for improved efficiency
Compatible workflow
Easily integrates with existing short-read sequencing assays and analysis pipelines
The value of Q40+ sequencing accuracy with SBB for liquid biopsy
“Our early access data demonstrates the ability to accurately detect ultra-low variants without the need for high-complexity error correction across a broad spectrum of applications, including infectious disease and liquid biopsy research.”
— Stephanie Pond, Vice President of Emerging Opportunities at TGen
Why SBB for liquid biopsy sequencing?
Variant detection performance was tested for SBB and SBS sequencing using the SeraCare Complete ctDNA Mutation Mix across five variant allele frequencies: 0% (WT), 0.05%, 0.1%, 0.25%, and 0.5%. The Onso system achieved nearly double the sensitivity for rare variant detection with equivalent coverage (left, 6,000X SBB UMI- vs 6,000X SBS UMI-). The Onso system also demonstrated equivalent or better performance with 4-fold less sequencing (right, 6,000X SBB UMI+ vs 24,000X SBS UMI+).

Next-level discovery in liquid biopsy
Liquid biopsy is revolutionizing oncology research through the non-invasive detection of tumor DNA. But are you confident your assay is seeing everything there is to discover?
Many existing liquid biopsy techniques rely on extreme sequencing depth and complex error-correction strategies to compensate for lackluster sequencing performance. Even so, there is so much more that is waiting to be discovered. Listening to the needs of the cancer research community, PacBio has introduced a next-generation liquid biopsy development solution with the Onso short-read sequencing system. This cutting-edge platform can enable you to detect ctDNA earlier, and with less sequencing thanks to the superior Q40+ accuracy of proprietary SBB chemistry.
The Onso short-read system for liquid biopsy
The Onso system has the potential to lower the limit of detection for ctDNA, improving sensitivity and reducing sequencing requirements. This enables the identification of variants missed by other short-read sequencing platforms.
SBB: Sequencing by binding
Proprietary SBB chemistry uses native nucleotides, scarless incorporation, and optimized conditions for binding and extension, resulting in data with decreased errors and improved performance in repetitive regions.

SUPERIOR SENSITIVITY FOR ctDNA DETECTION ON THE ONSO SYSTEM
Unlock the accuracy needed for liquid biopsy with the Onso system
Liquid biopsy, a noninvasive assay for circulating tumor DNA (ctDNA) in blood, holds the promise to revolutionize research on cancer detection and monitoring. Current sequencing by synthesis (SBS) approaches to liquid biopsy are constrained by their accuracy, which affects the limit of detection of rare variants. However, the introduction of the Onso system, powered by the extraordinary accuracy of sequencing by binding (SBB) chemistry, now enables the sensitivity necessary to detect low-frequency variants in liquid biopsy applications.
