01 — Sample qualification workflow

Derisk spatial assays with AtlasVerify.

A high-throughput in-situ bulk qualification assay on an adjacent section helps predict spatial assay performance before you commit your slides.

1
Prepare slides

Mount 5–10 µm sections on standard 1" × 3" slides (typically ~5 slides per sample), then ship to AtlasXomics.

2
In-situ qualification

We run an in-situ bulk qualification assay, generate an NGS library trace, and perform shallow sequencing (30–50M reads).

3
Evaluate performance

Review in-situ bulk peak signals (e.g., TSS enrichment, FRiP) to predict spatial performance on adjacent sections.

Why it matters: Spatial assays are expensive — sample qualification helps reduce failure risk from suboptimal blocks and increases confidence before scaling to full spatial profiling.

02 — Resources

In-situ bulk qualification assays derisk your spatial studies.

Learn how a simple qualification workflow can flag challenging FFPE blocks early, guide ROI selection, and help you move forward with confidence.

In-situ bulk qualification assays derisk your spatial studies

A practical guide to using AtlasVerify to evaluate tissue quality before spatial profiling — covering protocol, key QC metrics, and case examples across FFPE and fresh-frozen tissue types.

  • Will this tissue work for spatial ATAC?
  • Is permeabilization optimal for this block?
  • Is chromatin quality sufficient in this section?
  • Where is the best ROI for spatial profiling?
