Distilled water 150 mL Distilled water 150 mL
Eosin Y, ws 2.5 g Eosin Y, ws 2.5 g
      Phloxine B 1 g
      Orange G 1 g


Blue Buffer   Define
Distilled water 1 L Distilled water 1 L
Trizma base 10 g Citric acid 20 g
      Sodium citrate, monobasic 20 g


Expected results
The procedure was designed to be used with routinely fixed and paraffin processed tissues.


  1. Bring sections to water with xylene and ethanol.
  2. Place into the staining solution for the appropriate time.
  3. Rinse well with water.
  4. Differentiate with citric acid buffer.
  5. Rinse with water and blue with Trizma base solution.
  6. Rinse well with water.
  7. Counterstain with Surgipath Eosin 515 or Eosin 515 Trichrome.
  8. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected results



  1. The hemalum should have a pH of 2-3.
  2. The Eosin 515 and Eosin Trichrome 515 should have a pH of 4-5.
  3. The Define solutions should have a pH of 3-4.
  4. The Blue buffer should have a pH of 8-8.3.
  5. As the hemalum contains hydrochloric acid it may remove small calcium deposits. These are sometimes an indicator of disease, in malignant breast lumps, for example.
  6. Although the Blue buffer, Define and the two eosin solutions are designed to be used together, Other solutions may be substituted.
