IHC (Immunohistochemistry)

Immunohistochemistry (IHC) is a laboratory technique used to detect specific proteins in tissue samples, often from biopsies. It uses antibodies—engineered molecules that can bind to specific targets—to identify these proteins. By applying stains or markers, scientists can visualize where the proteins are located within the cells and tissues under a microscope. This helps pathologists diagnose diseases, including cancers, by revealing abnormal protein expressions that indicate disease presence or categorization. IHC is essential in understanding the biological behavior of tissues and guiding treatment decisions in medicine.
