免疫组化技术（Immunohistochemistry, IHC）是一种在组织切片中检测和定位蛋白表达的方法。通过将组织切片与特异性抗体反应，形成可视化的免疫复合物。使用染色剂或荧光标记可在显微镜下观察并定位目标蛋白。IHC 广泛用于癌症诊断、病理学研究和生物医学研究中，为了解组织中蛋白的表达和定位提供了关键信息。

Immunohistochemistry (IHC) is a method for detecting and localizing protein expression in tissue sections. Immune complexes are visualized by reacting tissue sections with specific antibodies. Target proteins can be visualized and localized under a microscope using stains or fluorescent labels. IHC is widely used in cancer diagnosis, pathology research, and biomedical research, providing key information for understanding the expression and localization of proteins in tissues.
