Blocker Displacement

Rare allele enrichment technology by PCR that enables the selective amplification and detection of low-abundant sequence variants down to 0.01% variant allele frequency (VAF).

Quantitative Amplicon

NGS-based method that utilizes unique molecular identifiers (UMIs) and highly multiplexed partially nested PCR primer design to detect mutations and copy number variations with high sensitivity.

VarMap® Pan-Cancer NGS Panel

The only liquid biopsy panel to detect 0.1% VAF requiring only 1 million NGS reads


The VarMap Pan-Cancer NGS Panel enables highly sensitive variant detection and quantitation across hundreds of loci in 61 genes. Utilizing BDA technology and next-generation sequencing, the VarMap Pan-Cancer panel significantly improves the limit of detection (≥0.1% VAF) while reducing the number of reads required. The panel is compatible with several sample types, including cell-free DNA, tumor sections, and PBMC DNA.

Key Features

  • Detect SNVs and indels down to 0.1% VAF
  • Requires only 1 million NGS reads per sample
  • Compatible with tumor-derived or cell-free DNA
  • Simple and user-friendly workflow and bioinformatics

CNV+ Breast Cancer NGS Panel

Accurately detect SNVs and indels in 14 genes and CNVs across 18 genes associated with breast cancer


The CNV+ Breast Cancer NGS Panel covers 84 frequently mutated breast cancer hotspots in 14 genes and CNVs of 18 genes including HER2. Using QASeq technology, the CNV+ Breast Cancer NGS Panel accurately quantifies SNVs and indels down to 0.2% VAF and detects CNVs in HER2 at 2.04/1.97 single heterozygous copy gain/loss from cfDNA or tumor tissue.

Key Features

  • Detect SNVs and indels at 0.2% VAF
  • Detect CNVs at 2.04/1.94 ploidy
  • Compatible with tumor-derived or cell-free DNA

Key Features

  • Matched normal not required
  • Results in less than two hours
  • Compatible with tumor tissue or cell-free DNA
  • Limit of detection down to 1% VAF

VarTrace® qPCR/Sanger Assays

qPCR/Sanger assays to identify variants down to 0.1% VAF
