High Sensitivity TSO500 Detection of Somatic Variants in Matched FFPE and Plasma: Implications for Liquid Biopsy Biomarker Evaluations
Presented by Shawn Levy, PhD (Discovery Life Sciences)
Watch this webinar to learn how Discovery leverages TSO500 sequencing capabilities to conduct a comparative analysis of paired plasma and FFPE samples, and more.
Applications
Our TSO500 NGS services provide pan-cancer genomic biomarker analysis to enable:
- Discovery and verification of the presence of genomic biomarker targets and signatures in liquid biopsy ctDNA
- Retrospective identification of potential oncology clinical trial patient responders versus non-responders based on genomic profiles
- RUO development and orthogonal validation of novel liquid biopsy diagnostic solutions
- Combine the matching TSO500 ctDNA and TSO500 Solid Tumor applications to develop and validate non-invasive liquid biopsy assays from matched-patient Plasma and FFPE samples
