Aceto Orcein
Aceto Orcein is a synthetic dye used primarily in histology and cytology for staining tissues. It’s known for its ability to selectively stain chromatin and nucleic acids, making it valuable for studying cell structures. The dye is often employed in research to highlight genetic material, allowing for clearer visualization of cellular components under a microscope. Its vivid coloration helps differentiate between different types of tissues and cellular elements.
