What You Need to Get Started

  • Input Material: Frozen tissues, cryopreserved cells, or fresh tissues and cells; detailed troubleshooting support included for low-viability samples
  • Sequencing: Illumina-compatible sequencing system
  • Bioinformatics: Standard ATAC-seq pipelines.
A PBMC IGV comparison shows EGT and VendorA ATAC-seq tracks together with histone-mark tracks, where EGT-unique ATAC peaks overlap the established active marks H3K27ac and H3K4me1.
In PBMC samples, Epigenome Technologies' ATAC-seq data better comports with active histone modifications than competitor kits and open protocols.

Why Teams Choose This Kit

The EGT ATAC-Seq Kit delivers reproducible, high-quality, high-complexity libraries with reference-aligned accessibility signal and a workflow built for confident downstream interpretation. Comparative data show strong performance across library complexity, mitochondrial-read fraction, correlation, TSS enrichment, and locus-level signal.

The ATAC kit from Epigenome Technologies provides high-complexity open chromatin data. In K562 cells, our kit better captures enhancer peaks (active but not marked by H3K4me3) than competitor approaches.

Built by Epigenetic Experts

Developed by a team focused on Tn5-driven epigenetics workflows, including demanding single-cell use cases, the ATAC-seq kit from Epigenome Technologies applies that expertise to reproducible bulk ATAC library preparation, including clear QC guardrails, and producing high-quality signal for downstream nucleosome positioning and fragmentomics analysis.

Built for 8X and 16X Throughput

Use 8 reactions for focused studies or 16 reactions for broader sample sets and repeat conditions while maintaining the same reproducible, high-quality workflow and QC framework across both configurations.

More Informative Sequencing Output

Epigenome Technologies libraries show greater measured complexity than the alternatives in the representative comparison set across both cell lines and heterogeneous tissues. The resulting pool of unique fragments captures more of the underlying biology for peak discovery, quantitative accessibility analysis, nucleosome positioning, and fragmentomics workflows.

This comparison shows extrapolated library complexity in K562 and PBMC across Epigenome Technologies' ATAC-seq kit and competitor approaches; the displayed EGT complexity is approximately 2 to 10 times higher than VendorA, indicating deeper capture of the underlying biology in these benchmark samples.

More Reads Available for Nuclear Signal

ATAC libraries from Epigenome Technologies show a robustly lower mitochondrial read fraction than the leading competitor, preserving more sequencing capacity for nuclear accessibility information. For low-viability tissues or cells, follow the validated Epigenome Technologies preparation, washing/debris-removal, and nuclei-quality guidance before transposition to reduce mitochondrial contamination and protect library quality.
