staining procedures

Staining procedures involve applying special dyes to biological samples, such as cells or tissues, to enhance visibility under a microscope. The process typically includes fixing the sample to preserve its structure, applying a stain that binds to specific components (like nuclei or cell walls), and then washing excess dye away. This contrast allows scientists to distinguish different parts of the sample, identify abnormalities, or analyze its composition. Staining techniques are essential in medical diagnostics, research, and education to visualize microscopic structures clearly and accurately.
