Feulgen stain

The Feulgen stain is a specialized chemical technique used in microscopy to detect DNA in cells. It involves treating cells with a reagent that specifically binds to DNA, making it visible under a microscope. This stain produces a pinkish color where DNA is present, allowing scientists to identify and measure DNA content within cell nuclei. The Feulgen stain is valuable in research and medical diagnostics for analyzing genetic material, studying cell division, or identifying abnormalities. Its specificity and clarity make it a useful tool for understanding cellular genetic information.
