nCounter Vantage™ Gene Fusion Panels
Multiplexed Gene Fusion Detection Simplified
NanoString’s Vantage panels for Lung and Leukemia gene fusion detection enable a highly multiplexed assay capable of simultaneously characterizing key fusion events and selected reference genes in a single tube. Combined with direct digital counting of the nCounter® system and our patented Junction Sequence probe design, the detection of fusion genes is highly sensitive, quantitative, and easy.
- Save time and sample material with multiplexed gene fusion detection in a single tube.
- Detect rare fusions with highly specific probes designed using patented Junction Sequence design technology.
- Ideal for use with challenging sample types including FFPE tissue.
- Customizable and forward compatible with our growing line of 3D Biology™ products.

Vantage Gene Fusion panels are created using one or more patented probe design methods.
Junction Probe Design: NanoString’s patented Junction Probe Design enables highly specific detection of fusion junction sequences. Specificity is conferred by toehold exchange technology that utilizes an additional probe, the Protector Probe, to create a thermodynamic balance that ensures signal is only generated in the presence of a perfect match of the target sequence.1,2 This enables highly specific detection of fusions in a background of abundant normal tissue.
FIGURE 1 Illustration of the junction probe design methodology. Junction probes span a unique fusion junction, using toehold exchange technology for greater specificity. For a technical explanation of toehold exchange technology, see Zhang DY, Chen SX, Tin P. (2012) Optimizing the specificity of nucleic acid hybridization. Nat Chem 4(3):208-14.
5’/3’ Positional Imbalanced Probe Gene Expression Design:
In some instances, fusion events can also be detected with a probe design that compares the ratio of gene expression upstream and downstream of a fusion junction. Each fusion partner may have promoters with different strength or activity, which will differentially affect expression of exons located 5’ or 3’ of this junction. A ratio of 5’/3’ expression that diverges from 1 is therefore indicative that a fusion event has occurred. The 5’/3’ design can be used to discover new fusions3 or to aid in the development of robust assays to support clinical research programs.4,5

Customize any Fusion Panel: nCounter Vantage Panels are available with the option to customize using our TagSet Extension product. With the additional purchase of the TagSet Extension product and custom designed probes, users can add up to 24-additional genes to any panel including:
- Additional Fusion Genes
- Disease or Tissue-specific genes
- Immune response genes
Fusion Data Analysis
Following hybridization with the nCounter Vantage Gene Fusion assay, samples are analyzed for fusion detection. Each target of interest is identified by the ‘barcode’ generated by six ordered fluorescent spots. The molecular barcode is then counted and tabulated for each target.
Detailed data analysis for Fusion panels is performed using our nSolver data analysis software. NanoString’s Field Application Scientists and Bioinformatics team can provide personalized training, data analysis and support.
