Several methods are used for cell labeling in histology, including:
Immunohistochemistry (IHC): Uses antibodies to detect specific antigens in cells, producing a visible color change. Fluorescent Labeling: Employs fluorescent dyes or proteins to mark cells, which can be visualized under a fluorescent microscope. In Situ Hybridization (ISH): Uses labeled nucleic acid probes to detect specific DNA or RNA sequences within cells. Radioactive Labeling: Involves incorporating radioactive isotopes into molecules within the cell, detectable via autoradiography. Enzyme-based Labeling: Utilizes enzymes that catalyze a reaction to produce a colored product in labeled cells.
