We deliver high-quality, customizable oligos across all synthesis grades — tailored to your technique, application, and compliance needs.
Tailored oligo solutions for
every assay
Diagnostic and testing professionals—from routine testing labs to IVD kit manufacturers—
require different levels of quality, documentation, and compliance depending on their project stage and application.
That’s why we offer a continuum of oligonucleotide grades—Research, Track™, pre-Diagnostic (pre-Dx) and Diagnostic (Dx)—each
designed to align with a specific phase of your assay lifecycle and your regulatory environment.

Freedom to operate with IP-free oligos
Using IP-free dyes and quenchers gives you full freedom to operate — with no licensing hurdles, no hidden royalties, and no restrictions on commercialization.
It also simplifies your regulatory file during CE-IVD or FDA submissions.
All IP-free oligos are available across RUO, Track™, pre-Dx and Dx grades.
We support diagnostic & testing applications
Our oligonucleotides are widely used in molecular diagnostics for human health, enabling early
detection, biomarker analysis, and disease monitoring with accuracy and speed. We also
supports non-clinical diagnostic testing in highly regulated sectors where precision and traceability are critical.
High-performance oligos for human diagnostic applications
Molecular diagnostics rely on accurate oligos to detect infectious diseases, cancer mutations, and genetic disorders with speed and confidence.
Oligos for infectious diseases, oncology, and genetic screening
Our oligonucleotides are optimized for human health diagnostics — including the detection of pathogens like SARS-CoV-2, HPV, tuberculosis, or cancer mutations like BRCA1/2, EGFR, and KRAS. Our primers and probes support multiplex qPCR, dPCR, LAMP, and next-generation sequencing (NGS/WES) for applications such as liquid biopsy, syndromic testing, and hereditary disease screening. Whether you're developing panels or running daily clinical tests, we ensure batch consistency and fast delivery. Oligos are available in multiple grades to meet the needs of LDTs, CE-IVD kits, and hospital labs. Built for accuracy and compliance, our solutions empower diagnostics at every stage.
Reliable oligos for species-specific pathogen detection
Veterinary diagnostics demand accuracy to detect pathogens in both livestock and companion animals, whether on-site or in testing laboratories.
Multiplex-ready solutions for animal health diagnostics
Our oligos support veterinary diagnostics for avian flu, swine flu, rabies, parvovirus, and more — enabling fast, species-specific detection. Whether testing in centralized labs or deploying point-of-care tools, our primers and probes are compatible with qPCR, PCR, and LAMP assays. Multiplex formats and custom modifications are available to support a wide range of workflows. Reliable detection of infectious agents in pets, farm animals, and wild populations helps protect animal health and food safety, with fast turnaround times and flexible batch sizes.
Protect food and feed safety with trusted oligos
Ensure authenticity, allergen screening, and pathogen detection with oligonucleotides tailored for regulatory testing and quality control labs.
Custom primers and probes for food testing
We supply high-quality oligos for routine food and feed diagnostics — from detecting pathogens like Salmonella and Listeria to confirming species identity (e.g., pork in halal beef) and identifying allergens (such as peanut) or gluten (through plant species detection). Our oligos are designed for high-throughput qPCR and multiplex assays, and are compatible with DNA barcoding methods. Ensure accurate, traceable results for regulatory submissions and internal quality processes. Whether you're screening raw materials or finished products, our oligos are trusted by food safety CROs and agri-food laboratories worldwide.
Plant pathogens detection and seed screening made easy
Oligos for testing plant health, identifying GMOs, and supporting disease resistance programs in agricultural diagnostics.
Oligos for phytodiagnostics and GMO testing
We offer tailored oligos for plant health and agricultural testing — including detection of Xylella fastidiosa, Fusarium, and other crop pathogens. Our probes also support GMO identification, seed purity testing, and molecular breeding programs. Compatible with multiplex qPCR, PCR and microarrays, our oligos enable high-throughput testing in compliance with regulatory standards. Whether you're monitoring disease spread or certifying seed quality, we provide consistent, well-documented oligos to support every step of your pipeline.
Sensitive detection of contaminants in water and soil
Environmental monitoring depends on robust oligos for microbial, viral, and antimicrobial resistance (AMR) gene detection in complex sample types.
Test for pathogens and resistance genes in the environment
Our oligonucleotides support microbial detection in water, wastewater, and soil samples — including E. coli, norovirus, and AMR genes (e.g., mecA, NDM). They are used in environmental DNA (eDNA) testing, surveillance programs, and contamination tracking. Whether working in public health, research, or environmental safety, our primers and probes are compatible with multiplex qPCR, NGS, and PCR workflows. Fast delivery and flexible grade options are available to match your project sensitivity and throughput needs.
Oligos for biologics and vaccine quality control
Ensure batch safety and compliance with oligos for QC testing in GMP and ISO 13485 environments.
Diagnostic-grade primers and probes for biopharma QC
Our oligos support QC testing across biologics, cell and gene therapies, and vaccine production — including residual DNA quantification, mycoplasma detection, and adventitious agent testing. Manufactured in ISO 7 and ISO 8 classified cleanrooms, our pre-Dx and Dx-grade oligonucleotides come with full documentation, Certificates of Analysis (CoAs), and batch traceability in compliance with ISO 13485 standards. We offer custom primers and TaqMan® probes for qPCR and dPCR, as well as expert guidance to help you maintain regulatory compliance and lot-to-lot consistency.
Specialized oligos for high-sensitivity and evolving assays
From rare diseases to forensic, epigenetic testing or companion diagnostics, our oligos support precision diagnostics in niche and emerging applications.
Tailored solutions for rare, genetic, and precision diagnostics
Our custom modified oligo support rare disease diagnostics (e.g. SMA, Duchenne, Huntington’s), forensic DNA testing (e.g. Y-STR, STR multiplex, mitochondrial DNA), and companion diagnostics (e.g. CYP450, EGFR) for targeted therapy decisions. We also support epigenetic studies with bisulfite-compatible primers for methylation-sensitive assays like Methylation specific PCR (MSP) or pyrosequencing. Whether you’re validating targeted therapy markers for personnalized medicine, or tracking resistance genes in public health surveillance, our qPCR and NGS-, WES- compatible oligos offer flexibility and quality.
