In addition to traditional stains, several advanced techniques have been developed:
1. Fluorescence Staining: Uses fluorescent dyes or antibodies to label specific cellular components. 2. In Situ Hybridization (ISH): Detects specific nucleic acid sequences within the tissue. 3. Multiplex Staining: Allows for the simultaneous detection of multiple targets in a single tissue section. 4. Electron Microscopy Staining: Uses heavy metals like osmium tetroxide to enhance contrast in electron microscopy.
