Designed for genetic analysis from limited amounts of sample tissue, the Oncomine Comprehensive Assay leverages Ion AmpliSeq technology to enable robust results from as little as 10 ng of nucleic acid extracted from an FFPE sample, per primer pool.*

To find the relevant few cancer drivers, this assay is part of a comprehensive solution—including Ion Torrent sequencing and Oncomine informatics—that enables NGS data analysis and includes a report with interpretations of the findings.


  • Analysis of 143 genes in one sequencing run, including >2,500 amplicons, 170 biomarkers, and 5 positive control genes
  • Hotpots, SNVs, indels, CNVs, and gene fusions from DNA and RNA in a single workflow
  • Content driven by the Oncomine Knowledgebase and industry experts helps assure coverage of key targets aligned to approved therapies and indications

  • Characterized with molecular standards and >300 FFPE samples
  • NGS results match those of verified single-gene tests (Table 1)
  • Additional relevant variants detected
  • Results verify the multiplexed PCR-based RNA-Seq approach for detecting targeted gene fusions
  • Reproducible and sensitive detection of variants across multiple cancer types
  • Robust performance from as little as 10 ng isolated from FFPE samples including fine needle biopsies
