10x Genomics obtained FFPE human kidney tissue from Avaden Biosciences. The tissue was sectioned as described in the Visium CytAssist Spatial Gene Expression for FFPE – Tissue Preparation Guide (CG000518). Tissue section of 5 µm was placed on a standard glass slide, then stained following the Deparaffinization, H&E Staining, Imaging & Decrosslinking Demonstrated Protocol (CG000520). The glass slide with tissue section was processed via Visium CytAssist instrument to transfer analytes to a Visium CytAssist Spatial Gene Expression Slide v2, with 11 mm capture areas following the Visium CytAssist Spatial Gene Expression Reagent Kits User Guide (CG000495).

- FFPE Block Age 3 years
- DV200: 42
The H&E image was acquired using Olympus VS200 Slide Scanning Microscope with these settings:
- Olympus Objective magnification: 20x UPLXAPO Objective
- Numerical Aperture: 0.8
- ScopeLED light source: Xcite Novum
- Camera: VS-264C
- Exposure: 500 µs
From the H&E image, the glomeruli and the tubular system, as part of the basic functional unit of the kidney can be identified. Two types of tubule (Distal convoluted tubule and proximal convoluted tubule) can be identified in the cortex structure content.
Libraries were prepared following the Visium CytAssist Spatial Gene Expression Reagent Kits User Guide (CG000495).
