Staining protocols

Staining protocols are laboratory methods used to add color to biological samples, enabling scientists to observe specific structures, cells, or tissues under a microscope. This process typically involves applying a dye that binds to particular components, allowing for visualization and differentiation of various elements within the sample. Common stains include hematoxylin and eosin, which highlight cell nuclei and cytoplasm, respectively. These protocols are essential in fields like pathology to diagnose diseases and in research to study cellular functions and structures. Proper staining enhances clarity and detail, facilitating accurate analysis and interpretation of the sample.
