Protocol

For formalin-fixed, paraffin-embedded (FFPE) tissue sections:

1. Deparaffinize in Xylene I for 6 minutes and II for 6 minutes.
2. Rehydrate: ethanol 100% (2 minutes)x2; ethanol 95% (2 minutes)x2; ethanol 70% (2 minutes)x1; Rinse in distilled water (5 minutes).Mordant in Bouin’s Solution, 60°C for 1 hour.
3. Prepare Weigert’s working hematoxylin: mix Weigert’s Hematoxylin Solution A and B at 1:1 ratio.
4. Weigert’s working hematoxylin for 10 minutes. (Note: Discard after use.)
5. Blue in running tap water for 5 minutes, rinse once for 1 min in distilled water.
6. Biebrich Scarlet-Acid Fuchsin Solution for 5 minutes. (Note: Solution may be used twice only, then discarded.)
7. Rinse once for 1 min in distilled water.
8. Phosphotungstic/phosphomolybdic acid solution for 10 minutes, discard solution.
9. Transfer directly into Aniline Blue Solution for 10 minutes.
10. Rinse once for 2-3 seconds in distilled water.
11. Acetic Acid Solution for 2-3 seconds, discards solution.
12. Dehydrate with 2 changes of 95% Ethanol and 2 changes of 100% Ethanol (2 minute per change).
13. Clear with 3 changes of xylene (5 minutes per change) and coverslip with Permount or other suitable organic mounting medium.

For Frozen Sections:

1. Fix frozen sections in 10% formalin (not Zinc) for 30 minutes.
2. Rinses in distilled water 3×3min.
3. Mordant in Bouin’s Solution, 60°C for 1 hour.
4. Wash in running tap water for 5 minutes to remove the picric acid.
5. Weigert’s working hematoxylin for 7 minutes. (Note: Discard after use.)
6. Blue in running tap water for 5 minutes, rinse in distilled water.
7. Biebrich Scarlet-Acid Fuchsin Solution for 5 minutes. (Note: Solution may be used twice only, then discarded.)
8. Rinse in distilled water.
9. Phosphotungstic/phosphomolybdic Acid Solution for 10 minutes, discard solution.
10. Transfer directly into Aniline Blue Solution for 5 minutes.
11. Rinse once for 2-3 seconds in distilled water.
12. 1% Acetic acid for 2-3 seconds , discard solution.
13. Dehydrate with 2 dip of 95% Ethanol and 2 changes of 100% Ethanol (2 minutes per change).
14. Clear with 3 changes of xylene (5 minutes per change) and coverslip with Permount or other suitable organic mounting medium.
