MeDIP-qPCR & hMeDIP-qPCR Services – Locus-Specific DNA Modification Validation
High-throughput assays uncover genome-wide candidates, but researchers often need locus-specific confirmation. MeDIP-qPCR and hMeDIP-qPCR deliver quantitative insight into 5mC and 5hmC at defined genomic regions, adding clarity and confidence to your epigenetic research.
Key Highlights
- Locus-specific quantification of 5mC and 5hmC
- Reliable follow-up to sequencing or array findings
- High sensitivity and reproducibility with built-in controls
- Publication-ready data presentation
From Genome-Wide Discovery to Locus-Specific Confidence
High-throughput assays such as WGBS, MeDIP-seq, or array profiling provide a powerful genome-wide overview of DNA methylation and hydroxymethylation. They are essential for identifying candidate regions and building the big picture. Yet when the focus shifts to a single promoter, CpG island, or regulatory element, researchers need confirmation that goes beyond statistical predictions.
This is where MeDIP-qPCR and hMeDIP-qPCR play a complementary role. By combining antibody-based enrichment with quantitative PCR, they deliver:
- Direct experimental confirmation – moving from computational signals to validated results.
- Quantitative resolution – ΔCt-based enrichment values that provide measurable confidence.
- Complementary strength – not a replacement for high-throughput assays, but the natural next step to refine and validate discoveries.
Together, genome-wide discovery and locus-specific validation form a complete workflow: broad exploration identifies where to look, while MeDIP-qPCR and hMeDIP-qPCR provide the clarity to confirm what truly matters.
Nuanced Touches That Strengthen Your Results
Not all enrichment-qPCR assays are equal. Subtle technical decisions can make the difference between ambiguous data and interpretable results. Our service pays attention to these critical details:
- Primer design support – either reviewing your sequences or designing new primers optimized for CpG density, GC content, and amplicon size.
- Comprehensive control strategy – including Input DNA for normalization, IgG negative controls, and positive reference regions to benchmark enrichment.
- Optimized enrichment conditions – controlled DNA fragmentation (400–500 bp) and validated antibodies specific for 5mC or 5hmC.
- Flexible scope – from single-locus validation to multi-gene panels, with workflows adapted to your research goals.
These technical refinements ensure that enrichment values are meaningful, reproducible, and ready to inform your next research step.

Service Workflow – From DNA to qPCR Readouts
Our workflow is designed to deliver locus-specific clarity while maintaining reproducibility at every step:
1. DNA Quality Control & Fragmentation
- Genomic DNA is assessed for integrity, then sheared into 400–500 bp fragments suitable for immunoprecipitation.
2. Denaturation & Sample Splitting
- DNA is denatured into single strands and divided into two groups: one for enrichment (IP) and one as the Input control.
3. Antibody Enrichment
- Target-specific antibodies capture either 5-methylcytosine (5mC) or 5-hydroxymethylcytosine (5hmC).
- Non-modified DNA fragments are washed away, leaving enriched DNA bound to antibody complexes.
4. DNA Purification
- The enriched DNA is released and purified, ensuring it is free of inhibitors for downstream amplification.
5. qPCR Detection
- Locus-specific primers amplify the regions of interest.
- Ct values are obtained for both IP and Input DNA.
6. Relative Enrichment Calculation
- Modification levels are quantified using ΔCt normalization, producing fold-enrichment values that reflect true biological differences.
Each stage integrates quality controls to safeguard data integrity, so the final readout is not only quantitative but also biologically meaningful.
