Differentiation solution comprises acidified ethanol or isopropanol that is used to decolourise hematoxylin stain. The duration of exposure to the solution determines the degree of decolourisation. Differentiation is a crucial step in hematoxylin-eosin staining to achieve the proper colour contrast necessary for visualisation, by selectively removing excess hematoxylin from the tissue section and leaving behind the desired staining intensity.
