The detection of TTF-1 in histological samples is typically carried out using immunohistochemistry (IHC). In this technique, specific antibodies that bind to TTF-1 are used to stain tissue sections. The presence of TTF-1 is then visualized using chromogenic or fluorescent labels. This method allows pathologists to determine the presence and distribution of TTF-1 in tissues, which can be crucial for diagnostic purposes.
