Differentiation Solution

Supplier: SIGMA ALDRICH MICROSCOPY

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.
