 Understanding Immunohistochemistry: A Deep Dive

Immunohistochemistry is a powerful and versatile technique that has revolutionized the fields of pathology, diagnostics, and biomedical research. At its core, IHC leverages the specificity of antibodies to detect and localize specific antigens within tissue samples. This method provides crucial insights into protein expression patterns, cellular processes, and disease mechanisms.

A. The IHC Process: A Step-by-Step Breakdown

1. Tissue Preparation and Fixation:

   - Samples are typically fixed in formalin and embedded in paraffin

   - Proper fixation is critical to preserve tissue morphology and antigen integrity

2. Sectioning:

   - Thin sections (usually 3-5 μm) are cut and mounted on glass slides

   - Consistency in section thickness is crucial for reproducible results

3. Antigen Retrieval:

   - Heat-induced epitope retrieval (HIER) or enzymatic methods are used

   - This step unmasks antigens that may have been altered during fixation

4. Blocking:

   - Non-specific binding sites are blocked to reduce background staining

   - Common blocking agents include serum, BSA, or commercial blocking solutions

5. Primary Antibody Application:

   - Specific antibodies targeting the antigen of interest are applied

   - Incubation times and conditions vary depending on the antibody and protocol

6. Secondary Antibody Application:

   - Labeled secondary antibodies that recognize the primary antibody are added

   - These are often conjugated to enzymes (e.g., HRP) or fluorescent molecules

7. Visualization:

   - For enzyme-linked systems, a substrate is added to produce a colored precipitate

   - Fluorescent systems are visualized directly under a fluorescence microscope

8. Counterstaining and Mounting:

   - Tissues are often counterstained to provide context (e.g., hematoxylin for nuclei)

   - Slides are mounted with coverslips for long-term preservation
