Learn about Xenium analysis
Overview
This dataset is a preview of the Xenium Prime solution using development versions of the Xenium Prime 5K Human Pan Tissue & Pathways Panel, assay user guide, and Xenium Onboard Analysis software.
How to view data
Interactively explore this dataset with the Xenium Explorer web demo ("Open web demo" above) or download the files to explore further on your desktop. Desktop Xenium Explorer v3.0 is required to view this dataset on your local computer - now available for download here.
See the Getting Started with Xenium Explorer page for general guidance navigating the web demo interface and these instructions to explore the aligned H&E image in the demo.
Biomaterials
FFPE-preserved tissues were purchased from Avaden Biosciences (Lymph Node, Left Axilla; Reactive Lymph Node).
Tissue preparation
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).
Probe hybridization, washing, ligation, amplification, and cell segmentation staining were performed following a development version of the Xenium Prime In Situ Gene Expression with optional Cell Segmentation Staining User Guide.
Post-instrument processing followed the Demonstrated Protocol Xenium In Situ Gene Expression - Post-Xenium Analyzer H&E Staining (CG000613).
Gene panels
The Xenium Prime 5K Human Pan Tissue and Pathways Panel was designed to enable comprehensive cell type and cell state identification using publicly available single cell RNA sequencing data. The panel also covers canonical signaling pathways, as well as genes relevant to developmental biology, immuno-oncology, and genes that are well known in biomedical literature.
A development version of the Xenium Human 5K Pan Tissue and Pathways Panel that targets 4,624 genes was used to generate this preview dataset. An additional 377 genes are targeted in the final version of the panel.
Xenium Analyzer
The instrument run was performed following the Xenium Analyzer User Guide CG000584. The on-instrument analysis was run with a development version of Xenium Onboard Analysis v3.0.0.
