How are Nucleic Acids Visualized in Tissue Samples?

Several staining techniques are employed to visualize nucleic acids in histological samples:
Hematoxylin and Eosin (H&E) Stain: Hematoxylin stains the nuclei blue, indicating the presence of DNA and RNA.
Feulgen Reaction: Specifically stains DNA, turning it magenta.
Methyl Green-Pyronin Stain: Differentiates DNA (green) and RNA (red).
In Situ Hybridization (ISH): Uses labeled probes to detect specific DNA or RNA sequences.
