Ordering
- VARIANTPlex™-HT Dx is a set of reagents and consumables used to prepare sample libraries, using manual and automated methods, from Nucleic Acid (DNA or TNA) extracted from fresh frozen or formalin-fixed, paraffin-embedded (FFPE) tissue or cells. User-supplied oligonucleotide panels are required for the preparation of libraries targeting specific genomic regions of interest.
- Registered with the FDA and IVDR compliant.
- Designed for an optimal user experience, featuring color-coded, technician- and robot-friendly reagents, fast workflows (1–1.5 days TAT, 3.5 hours hands-on time), and expert support for implementation and sustainment.
- Based on the Archer platform technology including our patented Anchored Multiplex PCR chemistry to empower molecular pathology laboratories with the right diagnostic products.
Each VARIANTPlex™-HT Dx kit contains an Archer™ Liquid Adapter Dx Kit (Set A or B ordered separately) orderable in both 24 & 96 reaction formats. All formats include VARIANTPlex™-HT Dx Liquid Reagents, Archer™ Cleanup Reagents, and the associated instructions for use.

Easier, more consistent benchtop work
Each kit includes color coded, technician and robot-friendly adapters, indexing primers, enzymes, buffers, and magnetic bead-based cleanup reagents. The workflow is consistent across formats, enabling efficient and reproducible library preparation.
Figure 1. Reagents are color-matched to protocol steps for easy benchwork. Each step of the protocol has a different color, which matches the packaging of the reagents (in this case liquid reagents) for that step.
High- throughput automation-ready for scalable workflows
96-reaction formats and standardized reagents offer compatibility and consistency with automated library preparation workflows. Liquid adapters are available in a 96-well plate format and feature over 36,000 unique dual index combinations to support high-throughput sequencing.
Sample input versatility and uniformity
The workflow accommodates both fresh-frozen and FFPE sample types, maintaining consistent incubation and cycling conditions across formats. This uniformity enhances reproducibility, streamlines training, and simplifies onboarding, which help lab personnel uphold high-quality standards with confidence.

Frequently asked questions
What is Anchored Multiplex PCR (AMP™)?
Anchored Multiplex PCR (AMP™) is a targeted next-generation sequencing (NGS) library preparation method designed to detect genomic alterations in challenging sample types, including highly degraded input materials like FFPE. AMP uses multiple “anchored” gene-specific primers (GSPs) that amplify opposite a single universal primer. This open-ended, anchored amplification makes AMP highly effective for discovering simple, novel, and complex rearrangements
Is VARIANTPlex™-HT Dx compatible with automated liquid handling robots?
Yes. VARIANTPlex-HT Dx reagents are compatible with both manual and automated library preparation methods.
What are the benefits of using TNA input for DNA-based library preparation?
Using TNA input for DNA-based library preparation simplifies laboratory workflows by enabling labs to leverage a single nucleic acid extraction method to generate input material for multiple downstream molecular workflows.
How does the VARIANTPlex-HT Dx workflow compare to the FUSIONPlex-HT Dx workflow?
Following DNA Fragmentation for VARIANTPlex-HT Dx and cDNA generation for FUSIONPlex-HT Dx, the workflow steps required to create sample libraries are the same for both products.
What sequencing platforms is VARIANTPlex-HT Dx compatible with?
VARIANTPlex-HT Dx libraries work with sequencing platforms that leverage P5 and P7 sequences to confer sequencer compatibility.
