Spatial Gene Expression dataset analyzed using Space Ranger 1.3.0
Learn about Visium analysis
10x Genomics obtained FFPE human breast tissue from BioIVT Asterand Human Tissue Specimens. The tissue was annotated with Ductal Carcinoma In Situ, Invasive Carcinoma. The tissue was sectioned as described in Visium Spatial Gene Expression for FFPE – Tissue Preparation Guide Demonstrated Protocol (CG000408). Tissue sections of 5 µm were placed on Visium Gene Expression slides, then stained following Deparaffinization, H&E Staining, Imaging & Decrosslinking Demonstrated Protocol (CG000409).

Annotations here were done at an overview level and were performed by Agoko NV, Belgium.
The H&E image was acquired using Metafer Slide Scanning Microscope from MetaSystems with these settings:
- Zeiss Plan-Apochromat 20x objective
- Numerical Aperture: 0.8
- ScopeLED light source
- MetaSystems CoolCube 4c camera
Libraries were prepared following the Visium Spatial Gene Expression Reagent Kits for FFPE User Guide (CG000407 Rev A).
