TSO500 ctDNA NGS Service for Liquid Biopsy

Streamlined parallel histopathology and NGS workflows to detect clinically relevant DNA and RNA variants in various solid tumor indications

HudsonAlpha Discovery’s TSO500 Solid Tumor NGS service provides high sensitivity detection of genomic variants across 523 DNA genes and 55 RNA Fusion events in most major cancer indications and sample types, including microsatellite instability (MSI) and tumor mutational burden (TMB) immuno-oncology biomarkers.
For Research Use Only.


Our TSO500 NGS services provide pan-cancer genomic biomarker analysis of SNVs, InDels, CNVs, Fusions, TMB, and MSI to enable:
  • Discovery and verification of the presence of genomic biomarker targets and signatures in solid tumors
  • Retrospective identification of potential oncology clinical trial patient responders versus non-responders based on genomic profiles
  • RUO development and orthogonal validation of novel solid tumor diagnostic solutions
  • Combine the matching TSO500 Solid Tumor and TSO500 ctDNA applications to develop and validate non-invasive liquid biopsy assays from matched-patient Plasma and FFPE samples

Service Performance Data

Using commercially available reference standards in our optimized and automated nucleic acid extraction, library construction, and sequencing workflows, we demonstrate the accuracy, sensitivity, and reproducibility of our TSO500 Solid Tumor NGS RUO service.
