GSM9198043: Ulcerative colitis patient 2 - terminal ileum biopsy, and rectum biopsy [UC02_TL_RE]; Homo sapiens; OTHER
Formalin-fixed paraffin-embedded (FFPE) tissue sections, 5 µm thick, were mounted on Visium HD slides (10x Genomics) using the CytAssist instrument according to the manufacturer's protocol. Sections were deparaffinized, rehydrated, and subjected to hematoxylin and eosin (H&E) staining following the 10x Genomics Visium HD FFPE tissue preparation guidelines. After imaging, RNA molecules were released and hybridized to slide-bound barcoded capture probes, enabling in situ capture of spatially resolved transcriptomes.
