Products support first-strand synthesis, genomic DNA removal and one-step or two-step reverse transcription PCR. QuantiTect and related products can simplify gene expression workflows.
Reliable expression analysis starts with high-quality RNA. Researchers should also use suitable reference genes and no-reverse-transcriptase controls.
The QIAcuity system provides nanoplate-based digital PCR for absolute nucleic acid quantification.
Digital PCR divides a reaction into many individual partitions. The instrument then counts positive and negative partitions to estimate target concentration.
Researchers use QIAcuity digital PCR for:
The QIAcuity workflow integrates partitioning, thermal cycling and imaging within one instrument. Different nanoplate formats support different throughput and sensitivity requirements.
Assay design remains important. Researchers should confirm primer and probe performance before using digital PCR for critical measurements.
QIAGEN offers products for sequencing library preparation, target enrichment and nucleic acid quality control.
QIAseq kits support applications such as:
Targeted panels can focus sequencing capacity on genes or genomic regions relevant to a research question. Unique molecular identifiers can help distinguish original molecules from amplification duplicates.
Researchers should verify sequencing platform compatibility, sample input and panel content before ordering.
PyroMark systems use pyrosequencing technology for targeted sequence analysis and quantification.
Researchers can apply these systems to methylation analysis, genotyping and mutation testing. Pyrosequencing provides quantitative information over short, defined sequence regions.
Successful assays require suitable primer design and PCR optimization. QIAGEN provides instruments, reagents and software for the workflow.
QIAGEN instruments automate nucleic acid purification and sample processing.
QIAcube Connect automates many spin-column procedures. This allows laboratories to use familiar QIAGEN kit chemistry with reduced manual handling.
QIAsymphony systems support automated sample preparation and assay setup in higher-throughput laboratories. EZ2 instruments use magnetic particle technology for automated purification.
Automation can improve consistency and reduce hands-on time. Laboratories should compare sample throughput, supported kits and instrument footprint before selecting a platform.
Effective disruption and homogenization help release nucleic acids from difficult samples.
TissueLyser instruments provide mechanical disruption using bead-based shaking. Researchers can process animal tissue, plants, bacteria and other sample types.
The correct beads, tubes and processing conditions depend on sample hardness and size. Excessive processing can heat samples and affect nucleic acid quality.
QIAxcel systems automate DNA and RNA fragment analysis using ready-to-use gel cartridges.
Researchers can use these instruments to assess PCR products, restriction fragments and nucleic acid quality. Automated separation reduces the manual steps associated with conventional slab gels.
The system can process multiple samples and generate digital results. Cartridge selection depends on the required resolution and fragment range.
QIAGEN products support microbial DNA and RNA extraction from stool, tissue, environmental samples and other complex matrices.
Microbial samples often contain inhibitors that affect amplification and sequencing. Specialized purification kits help remove contaminants while recovering microbial nucleic acids.
Researchers can combine extraction products with PCR, digital PCR and next-generation sequencing workflows. Standardized sample processing improves comparability between microbiome studies.
QIAGEN offers technologies for analyzing tumor tissue, circulating nucleic acids and cancer-associated variants.
Specialized extraction kits can recover nucleic acids from formalin-fixed tissue, plasma and other clinical research samples. PCR, digital PCR and sequencing products then support mutation and biomarker analysis.
Low-frequency variants require careful control of sample input and analytical sensitivity. Researchers should select methods according to the expected variant abundance.
QIAGEN products support vector characterization, gene expression analysis and molecular quality control during cell and gene therapy research.
Digital PCR can quantify viral vector genomes, residual DNA and copy number. Nucleic acid purification kits prepare samples for molecular testing.
Researchers should distinguish general research products from solutions designed for regulated manufacturing or clinical applications.
QIAGEN offers specialized sample preparation and molecular testing products for human identification and forensic laboratories.

Other QIAGEN software products support variant interpretation, biomedical knowledge management and clinical research.
Software licensing, database content and deployment options should be reviewed separately from laboratory products.
QIAGEN products support research across:
Start with the sample type and target molecule. Define whether the experiment requires DNA, RNA, plasmid DNA, cell-free nucleic acids or microbial nucleic acids.
Next, consider sample input, required yield, purity and throughput. Manual spin columns may suit smaller projects, while magnetic bead systems and automated instruments may suit repeated or higher-volume workflows.
For PCR and sequencing, confirm instrument compatibility and sample input requirements. For automated systems, verify that the selected reagent kit supports the instrument model.
