I have found that that this gives a pleasing tinctorial result:
Haematoxylin and Eosin
Principle
Traditional HE procedures generally worked poorly on GM sections, with
background staining of the plastic embedment and the loosening of sections from
glass slides when alcoholic eosin is used. Aqueous solutions tend to stain
poorly.
Sections are firstly stained with Celestine blue, followed by a regressive
Harris's haematoxylin (excess stain is removed from the plastic with acid
alcohol). The sections are then counterstained with buffered eosin Y/Phloxine B.
Solutions
1. Celestine Blue - Iron Alum
2. Harris's Haematoxylin
3. Buffer for Eosin Y/Phloxine B.
Solution A2.875ml Glacial Acetic acid in 500ml distilled water.
Solution B4.1g Sodium Acetate in 500ml distilled water.
150 ml Solution A + 350 ml Solution B. pH to 4.85.
4. Eosin Y/Phloxine B.
Eosin Y (CI 45380)5g.
Phloxine B (CI 45410) 0.5g.
Buffer500ml.
Add 2 crystals Thymol.
Technique
1. Hydrate sections.
2. Stain in Celestine Blue 15 minutes.
3. Wash in running water.
4. Stain in Harris's Haematoxylin 15 minutes.
5. Wash, differentiate and blue till surrounding plastic is clear.
6. Stain in buffered Eosin for 6 minutes.
7. Wash lightly in running water.
8. Differentiate in alcohol till surrounding plastic is clear.
9. Clear in Xylene and mount.

Hello All,
I was wondering if anyone has a good Hematoxylin and Eosin (H) staining
protocol for JB4 embedded specimens?
Thanks!
