Overview
This dataset is provided as part of the Technical Note: Post-Xenium In Situ Applications: Immunofluorescence, H&E, and Visium CytAssist Spatial Gene Expression (CG000709). Post-Xenium samples were compared to controls (samples not processed through the Xenium workflow) using 10 µm fresh-frozen (FF) serial sections.

Biomaterials
Mouse brain samples (FF, OCT-embedded) were obtained from Charles River Laboratories.
Tissue preparation
Prior to the Visium CytAssist Spatial Gene Expression workflow, 10 µm sections were either placed on Superfrost Plus Slides (Fisherbrand, PN 12-550-15) and used as controls (not processed with the Xenium workflow prior to CytAssist), or placed on Xenium slides for Xenium processing (post-Xenium).
FF mouse brain sections used for post-Xenium applications were generated using the Xenium Mouse Brain Gene Expression Panel. For more details on methods, see page 13 of the Technical Note.
