10X Genomics obtained fresh frozen human Invasive Lobular Carcinoma breast tissue from BioIVT Asterand. The tissue was embedded and cryosectioned as described in Visium Spatial Protocols – Tissue Preparation Guide Demonstrated Protocol (CG000240). Tissue sections of 10µm were placed on Visium Gene Expression slides and fixed and stained following Methanol Fixation, H&E Staining & Imaging for Visium Spatial Protocols (CG000160).
The tissue was AJCC/UICC Stage Group I, ER positive, PR positive, HER2 negative.
The H&E image was acquired using a Nikon Eclipse Ti2-E microscope with the following settings:
- Color camera
- 10X objective
- Numerical Aperture: 0.45
- Exposure: 20 ms
The Visium Gene Expression library (T1T2-A6) was prepared as described in the Visium Spatial Reagent Kits User Guide (CG000239) Rev D). Sequencing data was processed using Space Ranger.
