Abstract
This protocol describes the preparation, staining, and in situ spatial transcriptomic analysis of tissue sections using an integrated 10x Genomics workflow. Standardized procedures were followed for tissue processing, slide preparation, and staining to ensure consistency and quality. Modifications were applied where appropriate to optimize sample integrity. The 10x Genomics Xenium platform was employed for high-resolution spatial gene expression profiling, enabling detailed molecular characterization of tissue architecture.
Guidelines
This protocol needs prior approval by the users' Institutional Animal Care and Use Committee (IACUC) or equivalent ethics committee.
Safety warnings
This protocol needs prior approval by the users' Institutional Animal Care and Use Committee (IACUC) or equivalent ethics committee
Section Preparation
Block QC and sectioning according to CG000578 Rev E.
Post sectioning, all slides were dried overnight at 37C then put in the desiccator.
Xenium in-situ
Deparaffinization and decrosslinking is done according to CG000580: rev E.
Deparaffinization temperature and time is according to this 10x protocol, 60°C for 2 hours.
The segmentation kit staining is performed according to CG000749 Rev B.
Xenium Analyzer is used according to CG000584 Rev K.
Xenium v1 T9TWE2 panel is used comprising of 480 genes that were targeted with a fully custom 480-gene panel.
