Immunohistochemistry (IHC) products are essential tools for both clinical pathology and life science research. Clinically, they are pivotal for tumor diagnosis, lineage determination, molecular subtyping, targeted therapy selection, and prognostic assessment. In research, they enable protein localization, biomarker discovery, and drug development. Each reagent—from primary antibodies to differentiation solutions—plays a critical role in ensuring the success and accurate interpretation of IHC experiments.Immunohistochemistry, full name Immunohistochemistry (abbreviated as IHC), is a laboratory technique that uses antibodies to detect specific antigens (usually proteins) in tissue sections. It helps pathologists diagnose diseases by making the targets "visible" under a microscope.
