Sorry, I forgot our method for H&E's. Generally
speaking, people would use Gills hematoxylin and Eosin
or eosin/phloxine. Our pathologists didn't like the
look of Gills III. In 1980, after doing extensive
R&D, a light when on in my brain. Our nuclear
staining on our GMA PAS's were beautiful. We oxidized
in 10% periodic acid for 10 minutes for PAS. So, I
tried doing the same with the H&E's on GMA's. The
pathologists loved the results and said it looked like
a regular H&E.
I gave several workshops on this subject regarding GMA
H&E's and special stain,s but I can't find my hand-out
material. Sorry, it was back in the 80's.
Here is the procedure from the cobwebs of my brain:
1. After adhering section to slide, place GMA slide
directly into 10% Periodic Acid for 10 minutes.
2. Rinse in tap water for 1-2 minutes.
3. Place in Harris Hematoxylin for 15 to 20 minutes.
4. Rinse in tap water.
5. Quickly dip in 0.5% acid alcohol.
6. Rinse in tap water.
7. Blue in freshly prepared ammonia water.
8. Rinse in tap water for 10 minutes.
9. Counterstain in Eosin/Phloxine for desired length
of time. You can start with 1-2 minutes.
10. Dehydrate through graded alcohols quickly.
11. Clear and coverslip.
Hope this helps.
