Immunohistochemistry (IHC)

Immunohistochemistry (IHC), also known as Immunocytochemistry (ICC), is a technique based on the principle of antigen-antibody specificity in immunology (as illustrated in the figure below). Through chemical reactions, it utilizes chromogenic agents (such as fluorophores, enzymes, metal ions, or isotopes) to visualize labeled antibodies, enabling the identification of antigens (e.g., peptides and proteins) within cells or tissues. This experimental method is used to study antigen localization, as well as qualitative and quantitative analysis.
