ATAC-seq(Assay for Transposase-Accessible Chromatin using sequencing)は、ゲノムワイドなクロマチンアクセシビリティの査定を可能にします。 この技術は、トランスポゼースを利用してオープンクロマチンを切断すると同時に、増幅及び配列決定のアダプターと連結します。


  • 遺伝子調節への洞察を得て、オープンクロマチンシグネチャーを理解
  •  一塩基分解でヌクレオソーム位置を検出
  •  転写因子(TF)の占有率を明確にする
  • Tagmentation、ライブラリー調製シーケンシング、解析などの包括的なサポートサービス

  • 詳細

    ATAC-seq services include:

    Sample tagmentation

    • Lysis
    • Tagmentation using Diagenode's Tagmentase (Tn5 transposase)

    Library preparation

    • Library amplification
    • Library purification
    • QC on the ATAC-seq library (DNA concentration, analysis of library profile)
    • Library pooling

    Deep sequencing

    • Samples are sequenced on an Illumina ® platform, paired-end 2x75bp
    • 100 million raw reads on average are obtained per sample when pooling 3samples/lane (Hi-seq 4000). Sequencing depth will be adjusted to project dependent criteria.

  • バイオインフォマティック解析

    Standard analysis

    Quality check, alignment to reference genome and identification of enriched regions (peak calling).

    Provided files:

    • Report with sequencing statistics
    • Raw data in FASTQ format
    • FastQC reports
    • Alignment files in BAM format
    • Peak files in BED format

    Additional analysis on request:

    Differential accessibility analysis:

    Identification and annotation (human, mouse, rat, drosophila) of differential chromatin accessibility between samples.

    Provided files:

    • Report with summary of differential accessibility analysis and plots
    • Files containing differentially accessibility sites or unique peaks and breakdown of those in annotated regions: introns, exons, promoters, 1-to-5 kb upstream-TSS and intergenic regions for human, mouse, rat and drosophila.

    Annotation in genomic regions:

    Annotation of ATAC-Seq peaks with genomic regions: introns, exons, promoters, 1-to-5 kb upstream-TSS and intergenic regions for human, mouse, rat and drosophila.

    Gene ontology terms analysis:

    Enrichment analysis on gene sets. Gene Ontology terms that are overrepresented in differentially bound regions may indicate the underlying biological processes involved.

    Pathway analysis:

    Identify biochemical pathways in which genes associated with differentially methylated regions (or individual differentially methylated CpGs) may be overrepresented.  

    Visualization of specific genomic regions:

    Visualization of results (i.e. sequencing data, peaks) at specific genomic regions (e.g. genes, promoters) in publication-ready images (human, mouse, rat).

    Additional information

    Generated files will be available for download during 1 month and stored for an additional period of 3 months on Diagenode’s servers. Additional long-term storage of data is available upon request.  Original samples are stored at Diagenode during 12 months after project completion, but will be discarded once this time is exceeded. Return shipment of samples is available upon request.

    Inflammatory stress-mediated chromatin changes underlie dysfunction in endothelial cells
    Liu H. et al.
    Inflammatory stresses underlie endothelial dysfunction and contribute to the development of chronic cardiovascular disorders such as atherosclerosis and vascular fibrosis. The initial transcriptional response of endothelial cells to pro-inflammatory cytokines such as TNF-alpha is well established. However, very few ...
