Immunohistochemistry, or IHC, denotes the method of locating proteins in the tissue cells. This method uses antibodies to detect antigens. It is typically employed to detect and monitor the progress of cancer by means of detecting cancerous tumors. In this way, many specific markers have been discovered to enable the determination of different types of cancer, such as the carcinoembryonic antigen for colon cancer, or CD 117 for gastrointestinal stromal tumors.
