Ingredient Amount Function
Hematein 2 g Dye
Ammonium alum 15 g Mordant
Distilled water 700 mL Solvent
Methanol 150 mL Solvent
Glycerol 150 mL Stabiliser


Compounding procedure
Dissolve the Alum in 600 mL water.
Dissolve the hematein in 100 mL water.
Combine, and add the other ingredients.
The solution may be used immediately.


  1. Bring sections to water with xylene and ethanol.
  2. Place into the staining solution for an appropriate time.
  3. Rinse well with water.
  4. Differentiate with acid ethanol if necessary.

  7. Counterstain if desired.
  8. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected results


  1. This solution uses hematein instead of hematoxylin.
  2. The staining time should be determined by trial.
  3. Acid ethanol is 0.5% - 1% hydrochloric acid in 70% ethanol.
  4. Blueing is done with alkaline solutions such as hard tap water, Scott’s tap water substitute, 0.1% ammonia water, 1% aqueous sodium acetate, 0.5% aqueous lithium carbonate etc.
