Compounding procedure

Stock solution
Mix the water and ethanol together.
Dissolve the hematoxylin.
Add an excess of phosphomolybdic or molybdic acid.
Shake frequently over one month until there is a distinct colour change to a deep blue-black.
The staining improves with aging.


  1. Bring sections to water with xylene and ethanol.
  2. Optionally, place into solution A for 24 hours.
  3. Place into solution B for 12-24 hours.
  4. Differentiate with solution A if overstained.
  5. Wash in running tap water.
  6. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected results


  1. The Microtomist's Formulary and Guide specifies phosphomolybdic acid, but the Microtomists Vade Mecum specifies molybdic acid.
  2. It is recommended for developing nerve tissues.
