A validated multiplex immunohistochemistry protocol enables simultaneous multi-biomarker spatial analysis on human colorectal cancer organoid models.
- Comprehensive mIHC Workflow for Cancer Stemness, Epithelial Identity, and Tumor Microenvironment Profiling in FFPE Organoid Models
- Unlock Spatial Insights into colorectal Cancer Organoid Biology with High-Performance Tyramide Signal Amplification-Based Multiplex Detection
Human cancer organoids preserve key architectural and molecular characteristics of primary tumors, providing a powerful model system for studying tumor heterogeneity, cancer stem cell populations, epithelial differentiation, and epithelial-mesenchymal transition (EMT). Our FFPE-compatible multiplex immunohistochemistry (mIHC) solution enables simultaneous visualization of multiple biomarkers within human colorectal cancer organoid sections, combining high-sensitivity Tyramide Signal Amplification signal amplification technology, validated antibodies, optimized detection reagents, and workflow-compatible consumables. The ALDH1A1/EpCAM/CK20/LGR5/Vimentin biomarker panel provides comprehensive characterization of:
- Cancer stem-like cell populations
- Epithelial tumor identity
- Differentiation status
- EMT-associated phenotypes
- Tumor heterogeneity and spatial organization
Application Overview
Spatial Profiling of colorectal Cancer Organoids Using a 5-Plex Biomarker Panel
Recommended Marker Combination
Multiplex immunohistochemistry (mIHC) staining of ALDH1A1, EpCAM, CK20, LGR5 and Vimentin in human colorectal cancer organoids, which enables researchers to investigate the relationship between stemness, epithelial differentiation, and mesenchymal transition within the same spatial context.
