Coprofiling Assay

Map Gene Regulation and Expression with Spatial Context

Spatial CoProfiling simultaneously measures chromatin accessibility and RNA from the same tissue section—directly linking regulatory state to transcriptional output, pixel by pixel, within intact tissue architecture.

The assay is built on spatial ATAC–RNA-seq, first described in a 2023 Nature publication from the Fan Lab at Yale, which demonstrated near-single-cell resolution co-profiling of the epigenome and transcriptome in mammalian tissues.

Modalities
Spatial epigenomics + spatial transcriptomics

Simultaneous Spatial RNA and Chromatin Accessibility Profiling Reveals Regulatory Underpinnings of Metastatic Transition

Presented at AACR 2026, this poster applies spatial CoProfiling to paired primary breast tumor and liver metastasis tissue sections, directly mapping chromatin accessibility and gene expression in the same section to uncover regulatory programs driving metastatic adaptation.

  • Open chromatin detected ahead of RNA changes, revealing regulatory priming in select tumor clusters
  • Distinct transcription factor motif enrichment between primary breast tumor and liver metastasis
  • Integrated ATAC + RNA clustering identifies heterogeneous tumor states across tissue architecture
