Overview
Xenium Prime 5K In Situ Gene Expression with Cell Segmentation Staining data for human ovarian adenocarcinoma tissue (Fresh Frozen) using the Xenium Prime 5K Human Pan Tissue and Pathways Panel.
How to view data
Interactively explore data with Xenium Explorer by downloading the Xenium Output Bundle (or Xenium Explorer subset) file. The subset bundle contains the experiment.xenium, gene_panel.json, morphology_focus/ directory of multi-file OME-TIFF files, analysis_summary.html, cells.zarr.zip, cell_feature_matrix.zarr.zip, transcripts.zarr.zip, and analysis.zarr.zip files.
Note: For large Xenium datasets generated with XOA v3.0, such as this one, with > 200 million unique cell by transcript features (sparse matrix), Xenium Explorer does not support certain transcript and cell functions due to performance limits. See more information here.
See the Getting Started with Xenium Explorer page for more details. Follow these instructions to view the post-Xenium H&E image or image alignment file in Xenium Explorer.
Biomaterials
Fresh frozen tissue was purchased from BioIVT prior to in-house embedding in OCT (Ovary; Ovarian Adenocarcinoma).
Tissue preparation
Tissues were prepared following the Xenium In Situ - Fresh Frozen Tissue Preparation Handbook (CG000579).
Probe hybridization, washing, ligation, amplification, and cell segmentation staining were performed following the Xenium Prime In Situ Gene Expression with optional Cell Segmentation Staining User Guide (CG000760).
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.
Xenium Analyzer
The instrument run was performed following the Xenium Analyzer User Guide CG000584. The on-instrument analysis was run with Xenium Onboard Analysis v3.0.0.
