MaterialAmountFunction
Hematoxylin5.5 gDye
Aluminum acetate5 gMordant
Distilled water100 mLSolvent
100% ethanol5 mLSolvent

Compounding Procedure

  1. Dissolve the hematoxylin in ethanol.
  2. Dissolve the aluminum acetate in water.
  3. Combine.

Protocol

  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.
  5. Rinse with water and blue.
  6. Rinse well with water.
  7. Counterstain if desired.
  8. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected Results

  • Nuclei  –  blue
  • Background  –  as counterstain or unstained

Notes

  • This strong formula should, presumably, be left for some time to ripen.
  • The characteristics and recommended use were not given.
  • The staining time should be determined by trial.
  • Acid ethanol is 0.5% – 1% hydrochloric acid in 70% ethanol.
  • 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.

Safety Note

Prior to handling any chemical, consult the Safety Data Sheet (SDS) for proper handling and safety precautions.
