Immune cells can be identified in tissues using various histological techniques. One common method is immunohistochemistry (IHC), which involves the use of antibodies labeled with dyes or enzymes to detect specific antigens in tissue sections. These labeled antibodies bind to their target antigens, allowing visualization under a microscope. Another technique is immunofluorescence, which uses fluorescently labeled antibodies to detect antigens, providing high-resolution images of immune cells.
