HTG EdgeSeq
Immuno-Oncology Assay

The HTG EdgeSeq Immuno-Oncology Assay (I/O) quantitatively measures the expression of 549 human RNA transcripts believed to be involved in the innate and adaptive immune response to cancer. The I/O assay enables comprehensive phenotypic analysis of immune infiltrates, assessment of immune activation and regulatory mechanisms, and investigation of key immuno-checkpoints. The I/O assay utilizes our automated HTG EdgeSeq system coupled with the sensitivity and dynamic range of next-generation sequencing (NGS)-based detection, and can be performed in your lab using the HTG EdgeSeq system, from our VERI/O lab as a service, or at one of the Qualified Service Provider (QSP) sites.

Features and Benefits

  • Simultaneous, quantitative measurement of 549 transcripts believed to be associated with immune response
  • Extraction-free: reduce extraction-associated data bias and sample loss
  • Reliable, reproducible performance from a single formalin-fixed, paraffin-embedded (FFPE) needle core biopsy slide
  • Gain insights faster: results in as little as 36 hours
  • Simplified data analysis: raw numerical data output provided in Excel format

Performance

The HTG EdgeSeq chemistry combined with NGS-based detection measures mRNA and provides an accurate, reproducible profile of both high- and low-expression transcripts.

Eight FFPE tumor samples were lysed and run at seven different laboratory sites using the HTG EdgeSeq Immuno-Oncology Assay. The samples were then compared to baseline data generated from our VERI/O laboratory. Data were aligned using the HTG EdgeSeq parsing software, normalized to counts per million (CPM), and log2 transformed.

The high Pearson correlation coefficients (r) obtained demonstrate that the HTG EdgeSeq Immuno-Oncology Assay yields highly reproducible results across operators, laboratories, and sequencing instruments.

Applications

  • Develop expression signatures
  • Research biomarkers indicative of responders vs. non-responders to treatment
  • Monitor patient response to treatment over time
  • Assess signaling pathway activation in response to stimulus
  • Assess tumor micro-environment 
  • Profile tumor-infiltrating lymphocytes

While the markers typically used in IHC  immunophenotyping show a similar immune component in the two tumors (left chart), an assement using the HTG EdgeSeq Immuno-Oncology Assay shows differeniated response when an expanded set of genes is examined (right chart). Melanoma 1 appears to have a significant upregulation of Type I interferon-related genes while Melanoma 2 displays high levels of metastasis-associated genes.
