HTG EdgeSeq PATH Assay

The HTG EdgeSeq PATH Assay has been designed for retrospective gene expression profiling (GEP) to complement traditional immunohistochemistry (IHC) testing by allowing investigators to assess mRNA expression of 470 targets when tissue availability is limited. The assay enables a wide variety of applications, including pre-screening of samples to guide subsequent testing and development of novel gene signatures.

The HTG EdgeSeq PATH 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 detection of 470 mRNA targets, including those commonly assessed by IHC
  • 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

Sample Requirements

Sample Type HTG EdgeSeq PATH Assay

Larger sample input amounts must be diluted. Please consult the assay package insert and HTG EdgeSeq System User Manual for more details. 

FFPE TissueOne 5 µm section
Cells≥3,000 cells

Performance

Repeatability Between Days (Inter-Day)

The results from three HTG EdgeSeq assay runs performed on the same processor on different days (D1P1, D2P1, D3P1) were compared to each other. Figure 1 shows the distribution of Pearson’s, r, for inter-day comparisons.

Applications

Measure gene expression levels with the HTG EdgeSeq PATH Assay that can assess 470 genes using a 5 µm FFPE tissue section.  

This assay can:

  • Serve as a complement to IHC interpretation of results
  • Provide additional information when sample amount is limited
