10x Genomics obtained FFPE human prostate tissue from Indivumed Human Tissue Specimens. Original diagnosis with adenocarcinoma. The tissue was sectioned as described in Visium Spatial Gene Expression for FFPE – Tissue Preparation Guide Demonstrated Protocol (CG000408). Tissue sections of 10 µm were placed on Visium Gene Expression slides, then stained following Deparaffinization, Decrosslinking, Immunofluorescence Staining & Imaging Demonstrated Protocol (CG000410).
- Block 1E333_Tp11 Section 1
- Stage II

Antibodies used for immunofluorescence (IF) staining:
- Channel 1 = 1:100 Iba1/AIF-1 (Cell Signalling, Cat. No. 36618S)
- Channel 2 = 1:100 Vimentin (Cell Signalling, Cat. No. 9856S)
- Channel 3 = 1:5000 DAPI (Thermo Scientific, Cat. No. 62248)
- Blocking buffer: 1X PBS; 2% BSA; 0.1% Tween 20; 1 U/uL Roche Protector RNase Inhibitor (based on CoA)
