Immunohistochemistry (IHC) Staining Process Diagram | Lab Science Visual #11376 (License: Personal Use)

This diagram depicts the core principle of immunohistochemistry (IHC), where specific antigens expressed in fixed tissue sections are bound by a primary antibody. A secondary antibody, conjugated to a detectable label (here shown as a green fluorophore), recognizes the primary antibody to enable microscopic visualization. The process occurs on a glass slide, forming the basis for diagnostic pathology and biomarker studies.

Used in biomedical education, pathology training, and scientific publications to explain IHC methodology; targets students, researchers, and clinicians seeking to understand antibody-based tissue staining techniques.
