Staining

technique Staining techniques are widely used in microscopy to enhance contrast in samples, allowing for easier and clearer visualization of structures and components of cells and tissues. A common staining technique is the use of dyes, which are applied to the sample to reveal different components. Depending on the type and combination of dyes used, it is possible to selectively demonstrate different parts of a sample. For example, the combination of dyes known as Gram stain is used to differentiate between types of bacterial cells. Staining techniques are essential in both research and clinical practice, as they are invaluable tools used in the diagnosis of diseases.
