Various microscopy techniques are employed in histology, including light microscopy, fluorescence microscopy, and electron microscopy. Light microscopy is the most common, used for routine examination of stained tissue sections. Fluorescence microscopy, often coupled with IHC or ISH, allows visualization of fluorescently labeled molecules. Electron microscopy, including transmission (TEM) and scanning (SEM), provides high-resolution images of tissue ultrastructure, revealing details at the nanometer scale.
