FFPE Human Breast using the Entire Sample Area

Demonstration of the Xenium platform's large imaging sample area, which enables high resolution and high throughput gene expression profiling. Replicate results demonstrate the high reproducibility of data generated by the platform.

The data were generated with the pre-designed Xenium Human Breast Gene Expression Panel (v1).

5µm sections from a formalin-fixed paraffin-embedded (FFPE) human breast resected tumor mass sample:

• Infiltrating Ductal Carcinoma (from Avaden Biosciences)

Tissues were prepared following the demonstrated protocols Xenium In Situ for FFPE - Tissue Preparation Guide (CG000578) and Xenium In Situ for FFPE Tissues – Deparaffinization & Decrosslinking (CG000580).

Post-instrument processing followed the demonstrated protocol Xenium In Situ Gene Expression - Post-Xenium Analyzer H&E Staining (CG000613). The registered H&E image file provided below is suitable for annotating regions. It may or may not be suitable for more refined exact sub-cellular resolution correspondence due to minute differences in the optics of the microscopy systems.

How to view data

Shared files are displayed in the Inputs/Slide tab and per-sample output files are in the Replicate tabs. Interactively explore data with Xenium Explorer by downloading the Xenium Output Bundle file. Load the Gene Groups CSV to create gene groups based on cell type markers. Follow these instructions to view the post-Xenium H&E image in Xenium Explorer.
