10x Genomics obtained FFPE Mouse Embryo tissue blocks from Avaden Biosciences. The tissue was sectioned as described in Visium CytAssist Spatial Gene Expression for FFPE – Tissue Preparation Guide Demonstrated Protocol CG000518. Tissue sections of 5 µm was placed on a standard glass slide, and H&E-stained following deparaffinization. Sections were coverslipped with 85% glycerol, imaged, decoverslipped, followed by dehydration & decrosslinking (Demonstrated Protocol CG000520). The glass slide with the tissue section was processed with the Visium CytAssist instrument to transfer analytes to a Visium CytAssist Spatial Gene Expression slide (11 mm Capture Area). The probe extension and library construction steps follow the standard Visium for FFPE workflow outside of the instrument.
The H&E image was acquired using an Olympus VS200 Slide Scanning Microscope with the following settings:
- Olympus Objective magnification: 20x UPLXAPO Objective
- Numerical Aperture: 0.8
- ScopeLED light source: Xcite Novum
- Camera: VS-264C
- Exposure: 410 µs
Libraries were prepared following the Visium CytAssist Spatial Gene Expression Reagent Kits for FFPE User Guide (CG000495).
