Immunohistochemistry and Immunofluorescence Approaches in Cancer Research Using Paraffin-Embedded Tissue Sections

Area of Science:

• Biomedical research
• Molecular biology
• Immunology

Background:

• Immunohistochemistry (IHC) and immunofluorescence (IF) are essential for high-resolution protein analysis in tissue architecture.
• These techniques are vital for characterizing signaling pathways and cellular phenotypes in normal and pathological conditions.
• Understanding protein distribution aids in investigating tumor biology, microenvironment, and therapeutic responses.

Purpose of the Study:

• To present comprehensive and reproducible protocols for chromogenic and fluorescent immunodetection strategies.
• To emphasize methodological details and key considerations for successful immunodetection.
• To provide widely applicable protocols for basic, translational, and clinical research.

Main Methods:

• Detailed protocols for immunohistochemistry (IHC) and immunofluorescence (IF) are presented.
• Emphasis on methodological details and key considerations for tissue section analysis.
• Protocols optimized for formalin-fixed, paraffin-embedded (FFPE) tissues.

Main Results:

• The chapter provides detailed protocols for both chromogenic- and fluorescent-based immunodetection.
• The presented methods are optimized for formalin-fixed, paraffin-embedded (FFPE) tissues.
• The protocols are compatible with a wide range of solid tumors and research models.

Conclusions:

• Immunohistochemistry (IHC) and immunofluorescence (IF) protocols offer powerful tools for cancer and immunology research.
• The presented methods enable precise spatial mapping and characterization of protein distribution.
• These protocols are broadly applicable to diverse research settings, including basic, translational, and clinical studies.
