Perform MeDIP (Methylated DNA Immunoprecipitation) followed by qPCR or NGS to estimate DNA methylation status of your sample using a highly sensitive 5-methylcytosine antibody. Our MagMeDIP kit contains high quality reagents to get the highest enrichment of methylated DNA with an optimized user-friendly protocol.


  • Starting DNA amount: 10 ng – 1 µg
  • Content: all reagents included for DNA extraction, immunoprecipitation (including the 5-mC antibody, spike-in controls and their corresponding qPCR primer pairs) as well as DNA isolation after IP.
  • Application: qPCR and NGS
  • Robust method, superior enrichment, and easy-to-use protocol
  • High reproducibility between replicates and repetitive experiments
  • Compatible with all species

  • MagMeDIP workflow

    DNA methylation occurs primarily as 5-methylcytosine (5-mC), and the Diagenode MagMeDIP Kit takes advantage of a specific antibody targeting this 5-mC to immunoprecipitate methylated DNA, which can be thereafter directly analyzed by qPCR or Next-Generation Sequencing (NGS).

    How it works

    In brief, after the cell collection and lysis, the genomic DNA is extracted, sheared, and then denatured. In the next step the antibody directed against 5 methylcytosine and antibody binding beads are used for immunoselection and immunoprecipitation of methylated DNA fragments. Then, the IP’d methylated DNA is isolated and can be used for any subsequent analysis as qPCR, amplification, hybridization on microarrays or next generation sequencing.

  • MeDIP-qPCR

    The kit MagMeDIP contains all reagents necessary for a complete MeDIP-qPCR workflow. Two MagMeDIP protocols have been validated: for manual processing as well as for automated processing, using the Diagenode’s IP-Star Compact Automated System (please refer to the kit manual).

    • Quality control of the IP: due to methylated and unmethylated DNA spike-in controls and their associated qPCR primers
    • Easy to use with user-friendly magnetic beads and rack
    • Highly validated protocol
    • Automated protocol supplied
    Methylated DNA Immunoprecipitation

    Figure 1. Immunoprecipitation results obtained with Diagenode MagMeDIP Kit

    MeDIP assays were performed manually using 1 µg or 50 ng gDNA from blood cells with the MagMeDIP kit (Diagenode). The IP was performed with the Methylated and Unmethylated spike-in controls included in the kit, together with the human DNA samples. The DNA was isolated/purified using DIB. Afterwards, qPCR was performed using the primer pairs included in this kit.

  • MeDIP-seq

    For DNA methylation analysis on the whole genome, MagMeDIP kit can be coupled with Next-Generation Sequencing. To perform MeDIP-sequencing we recommend the following strategy:

    • Choose a library preparation solution which is compatible with the starting amount of DNA you are planning to use (from 10 ng to 1 μg). It can be a home-made solution or a commercial one.
    • Choose the indexing system that fits your needs considering the following features:
          • Single-indexing, combinatorial dual-indexing or unique dual-indexing
          • Number of barcodes
          • Full-length adaptors containing the barcodes or barcoding at the final amplification step
          • Presence / absence of Unique Molecular Identifiers (for PCR duplicates removal)
    • Standard library preparation protocols are compatible with double-stranded DNA only, therefore the first steps of the library preparation (end repair, A-tailing, adaptor ligation and clean-up) will have to be performed on sheared DNA, before the IP.

    CAUTION: As the immunoprecipitation step occurs at the middle of the library preparation workflow, single-tube solutions for library preparation are usually not compatible with MeDIP-sequencing.

    • For DNA isolation after the IP, we recommend using the IPure kit v2 (available separately, Cat. No. C03010014) instead of DNA isolation Buffer.
    • Perform library amplification after the DNA isolation following the standard protocol of the chosen library preparation solution.

    MagMeDIP qPCR Kit Result

    Figure 1. qPCR analysis of external spike-in DNA controls (methylated and unmethylated) after IP. Samples were prepared using 1μg – 100ng -10ng sheared human gDNA with the MagMeDIP kit (Diagenode) and a commercially available library prep kit. DNA isolation after IP has been performed with IPure kit V2 (Diagenode).

    Figure 2. Saturation analysis. Clean reads were aligned to the human genome (hg19) using Burrows-Wheeler aligner (BWA) algorithm after which duplicated and unmapped reads were removed resulting in a mapping efficiency >98% for all samples. Quality and validity check of the mapped MeDIP-seq data was performed using MEDIPS R package. Saturation plots show that all sets of reads have sufficient complexity and depth to saturate the coverage profile of the reference genome and that this is reproducible between replicates and repetitive experiments (data shown for 50 ng gDNA input: left panel = replicate a, right panel = replicate b).

    Figure 3. Sequencing profiles of MeDIP-seq libraries prepared from different starting amounts of sheared gDNA on the positive and negative methylated control regions. MeDIP-seq libraries were prepared from decreasing starting amounts of gDNA (1 μg (green), 50 ng (red), and 10ng (blue)) originating from human blood with the MagMeDIP kit (Diagenode) and a commercially available library prep kit. DNA isolation after IP has been performed with IPure kit V2 (Diagenode). IP and corresponding INPUT samples were sequenced on Illumina NovaSeq SP with 2x50 PE reads. The reads were mapped to the human genome (hg19) with bwa and the alignments were loaded into IGV (the tracks use an identical scale). The top IGV figure shows the TSH2B (also known as H2BC1) gene (marked by blue boxes in the bottom track) and its surroundings. The TSH2B gene is coding for a histone variant that does not occur in blood cells, and it is known to be silenced by methylation. Accordingly, we see a high coverage in the vicinity of this gene. The bottom IGV figure shows the GADPH locus (marked by blue boxes in the bottom track) and its surroundings. The GADPH gene is a highly active transcription region and should not be methylated, resulting in no reads accumulation following MeDIP-seq experiment.

    Gene body DNA hydroxymethylation restricts the magnitude oftranscriptional changes during aging.
    Occean J. R. et al.
    DNA hydroxymethylation (5hmC) is the most abundant oxidative derivative of DNA methylation (5mC) and is typically enriched at enhancers and gene bodies of transcriptionally active and tissue-specific genes. Although aberrant genomic 5hmC has been implicated in many age-related diseases, the functional role of the mo...
