Iron Hematoxylin

Solution A Amount Function
Hematoxylin 2.5 g Dye
Dioxane 40 mL Solvent
Hydrogen peroxide 1 mL oxidiser
 
Solution B Amount Function
Ferric ammonium sulphate 3 g Mordant
Ferric chloride 1.5 g Mordant
Ferrous chloride 6 g Mordant
Distilled water 60 mL Solvent
Acetic acid 6 mL Acidifier

 

Compounding procedure
Dissolve the hematoxylin into the dioxane.
Add the peroxide.
Add the acetic acid to the water.
Dissolve the iron salts into the dilute acetic acid.
Filter the solution of iron salts into the hematoxylin solution.

Method

  1. Bring sections to water with xylene and ethanol.
  2. Place into the staining solution for an appropriate time.
  3. Wash well in running tap water to blue.
  4. Rinse with distilled water.
  5. Counterstain if desired.
  6. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected results

Notes

  1. The solution is likely stable for some time.
  2. Dioxane is no longer used in histotechnology for safety reasons. The method should be considered obsolete.
  3. The solution is progressive, and the staining time should be determined by trial.
