What does immunohistochemistry AR mean?

Immunohistochemistry (IHC) is a technique that uses immunological methods to detect the localization and distribution of specific antigen molecules within tissues or cells. Its fundamental principle involves the specific binding between antigens and their corresponding antibodies on tissue or cell specimens, followed by observation under light or electron microscopy to determine the location, distribution, and intensity of the antigens, thereby indirectly assessing the level of antigen expression. IHC can be used to identify whether a particular protein is present in cells and tissues, its precise location, and its relative expression level. Additionally, IHC enables the study of protein expression in different pathological cells and its impact on disease states. This technique is also valuable for detecting the expression and localization of antigens in cells and tissues, thus helping us better analyze pathological changes in cells and tissues.
