  • Compatible with 10-500 ng DNA from whole blood or bone marrow lysate (AML Panel), 1 tube of reaction
  • Compatible with MinION and Flongle flow cells
  • Requires only 30 minutes of sequencing time on MinION for up to 24 samples per run

Sample Data

Minimum Residual Disease
  • Horizon Myeloid reference sample (HD829) – 15,000 haploid copies ~ 50 ng was tested using the VarMap AML panel.
  • 100% concordance in variant calling.
AML Mutation Detection
  • Summary of VarMap nanopore results for 25 clinical cancer samples (7 fresh/frozen, 18 FFPE).
  • Relative to the NGS results, VarMap had a sensitivity of 100 % and a specificity of 99%.
  • The numbers in quadrant display the number of loci in each group. Purple dots represent variants that passed the variant call filter. 22/23 variant calls below NGS sensitivity were confirmed by ddPCR.


Workflow Step 1

Step 1: DNA Extraction

DNA is extracted from clinical samples with commercial extraction kits such as QIAamp® DNA Blood Mini Kit.

In patients with Acute Myeloid Leukemia (AML), several genes are frequently mutated, including FLT3, IDH1, IDH2, DNMT3A, KIT, and NPM1. The presence of these specific mutations can guide treatment with targeted therapies such as RYDAPT® (midostaurin), XOSPATA® (gilteritinib), TIBSOVO® (ivosidenib), and IDHIFA® (enasidenib).

The VarMap™ AML Nanopore Panel enables highly sensitive detection and quantification of mutations for AML patients. The kit uses NuProbe’s PCR-based Blocker Displacement Amplification (BDA) technology to enable the selective amplification of low abundant sequence variants (SNV and indels) in a background of wildtype DNA. Following PCR enrichment, Nanopore sequencing is applied to reveal the identity of the variants.
