Oncomine Precision Assay
Next-generation oncology solution
The Oncomine Precision Assay on the Ion Torrent Genexus System is a next-generation genomic profiling solution that can allow every laboratory to deliver a genomic profile with a one-day, hands-free workflow.†
The Oncomine Precision Assay on the Ion Torrent Genexus System is a next-generation solution for genomic profiling that’s accessible for laboratories of all sizes. Now labs can employ a hands-off workflow to detect key biomarkers such as EGFR, ALK, BRAF, ROS1, NTRK, RET, or ERBB2 from formalin-fixed paraffin-embedded (FFPE) tissue or liquid biopsy specimens in one day.
- Mutation, CNV, and fusion variant types across 50 key genes such as EGFR, ALK, BRAF, ROS1, RET, KRAS, PIK3CA, and ERBB2, among others
- One-day, hands-free workflow with only two touch points and 10 minutes of hands-on time
- Only 10 ng of DNA/RNA required, allowing for more samples to be tested
- Compatible with FFPE tissue as well as liquid biopsy samples
Oncomine Precision Assay content
Featuring the most prevalent and potentially relevant cancer driver variants across 50 genes, including potentially important resistance driving variants, this assay is ideal for fast genomic profiling in clinical cancer research.
Low input, high success rate
Some NGS send-out labs have test failure rates of 20% due to their high input requirement. At that rate, one out of every five samples submitted will not pass due to lack of tissue, and many more are never submitted for testing at all.
Not with Oncomine Solutions.
You can experience a sequencing success rate of over 95% with Oncomine assays, because we only require 10 ng of nucleic acid input. That means you can get an NGS result for most of the precious samples you have.
FFPE tissue and liquid biopsy compatible
In the drive to profile every important cancer sample, the tissue is still an issue, especially in some types of cancer such as non-small cell lung cancer (NSCLC). The Oncomine Precision Assay can deliver results from FFPE tissue as well as liquid biopsy if tissue is not available and can also be used for follow up to monitor the cancer profile development
FusionSync detection technology
There are a number of known and recurrent fusion isoforms that constitute a majority of the fusions detected. Having specific designs for these isoforms is important to maximize detection, even in challenging situations when sample input or transcript levels are low.
The optimized, synced design of the Oncomine Precision Assay enables comprehensive, sensitive fusion detection (including novel fusions in select driver genes) at low transcript or input levels.
- Targeted known-fusion detectionfor the most common and prevalent fusion isoforms (e.g., EML4 -ALK, ETV6-NTRK3, KIF5B-RET, etc.)
- Non-targeted detection of novel fusion combinations of targeted driver and partner genes
- Novel fusionsdetection by proprietary exon tiling imbalance method

Note: Testing was performed at multiple internal R&D laboratories as part of product verification testing. Samples were run at different plexy levels. Additional verification and validation testing will be performed using the Oncomine Precision Assay and FFPE controls; therefore final performance values can change.
