Compare Assays — AtlasXomics

Four assays, one platform

Each assay targets a different layer of epigenomic regulation. Click through to the full assay page for protocols, data examples, and support material.

All assays run on the FlowGel platform — 10 × 10 µm resolution, 48,400 spots per chip, 5.5 × 5.5 mm capture area.

ATAC-seq

Spatial ATAC-seq

Map open chromatin and regulatory element activity across intact tissue at spatial resolution.

Fresh frozen FFPE
Measures Chromatin accessibility (open chromatin)
Best for Cell type mapping, regulatory programs, tumor microenvironment
Analysis tools ArchR, SnapATAC2, Seurat, Signac, Scanpy
CUT&Tag

Spatial CUT&Tag

Profile histone modifications spatially to map active, repressed, and poised chromatin states.

Fresh frozen
Measures Histone modifications (H3K27me3, H3K4me3, others)
Best for Active/repressed gene regulation, developmental biology, cancer epigenetics
Analysis tools ArchR, Seurat, Signac, Scanpy, custom pipelines
Co-profiling

Spatial Co-profiling

Simultaneously capture chromatin accessibility and gene expression from the same tissue section in a single run.

Fresh frozen
Measures Chromatin accessibility (ATAC) + RNA gene expression
Best for Linking regulatory programs to transcriptional output, cell type annotation, multi-modal integration
Analysis tools Seurat, SnapATAC2, SpatialGlue, Squidpy, Scanpy, custom pipelines
Methylation

Spatial DNA Methylation

Profile genome-wide DNA methylation spatially across intact tissue. Two versions available — open chromatin + methylation now, genome-wide by end of year.

Fresh frozen
Measures 5mC / 5hmC DNA methylation at CpG sites
Versions Available now ATAC + TAPS — open chromatin + methylation co-profiled in a single run End of year Genome-wide methylation — standalone whole-genome methylation profiling
Best for Cancer methylation, epigenetic aging, imprinting, regulatory element methylation
Analysis tools SnapATAC2, Bismark, RASTAIR, Scanpy

Which assay fits your research?

Common experimental scenarios and the assay or combination we'd recommend for each.

Tumor microenvironment profiling

Identify cell-type-specific regulatory programs across tumor, stroma, and immune compartments. Map chromatin states to spatial location within the tissue architecture.

FFPE clinical cohort

Working with archival formalin-fixed tissue? ATAC-seq and TAPS+ are optimized for FFPE. Start with AtlasVerify to qualify samples before committing your cohort.

Active vs. repressed gene regulation

Profile H3K4me3 (active promoters) and H3K27me3 (polycomb repression) spatially to understand bivalent chromatin states and lineage commitment across tissue zones.

Spatial CUT&Tag

Developmental biology

Map epigenetic reprogramming and chromatin remodeling across developmental stages. Combine accessibility and histone marks for a comprehensive regulatory picture.

Multi-modal epigenomic integration

Capture chromatin accessibility and DNA methylation from the same tissue section in a single run — ideal for studies requiring both regulatory layers without doubling sample consumption.

TAPS+ / Co-profiling

Epigenetic aging and methylation clocks

Spatially resolve DNA methylation patterns associated with biological aging, epigenetic clocks, and disease-associated CpG changes — with tissue context preserved.
