What is the reason for using glycerol in H&E?

Explanation:
Glycerol is used as a stabilizer in H&E staining. Hematoxylin solutions can deteriorate or oxidize over time, which changes the intensity and hue of nuclear staining. Adding glycerol helps keep the stain solution stable by acting as a humectant and solvent that slows oxidation and evaporation, promoting consistent, reliable coloration of nuclei across slides and over time. It is not a dehydrating agent, clearing agent, or fixative, which is why the stabilizer role is the best fit.
