Die Differenzierungslösung besteht aus angesäuertem Ethanol oder Isopropanol, das zum Entfärben von Hämatoxylin-Färbung verwendet wird. Die Dauer der Einwirkung der Lösung bestimmt den Grad der Entfärbung. Die Differenzierung ist ein entscheidender Schritt bei der Hämatoxylin-Eosin-Färbung, um den richtigen Farbkontrast zu erzielen, der für die Visualisierung erforderlich ist, indem überschüssiges Hämatoxylin selektiv aus dem Gewebeschnitt entfernt wird und die gewünschte Färbungsintensität zurückbleibt.
