Components:

Luxol Fast Blue MBS Solution 0.1%

Cresyl Violet Acetate Solution 0.1%

Acetic Acid 10% Aqueous

Lithium Carbonate Solution 0.05%


Fixation:

Formalin, 10% Buffered Neutral


Sections:

Paraffin @ 15 to 20µm


Staining Procedure: 

  1. Deparaffinise and hydrate to 95% alcohol.
  2. Leave in Luxol Fast Blue Solution in 56°C oven overnight.
  3. Rinse off excess stain with 95% alcohol.
  4. Rinse in distilled water.
  5. Differentiate the slides singly in Lithium Carbonate Solution for 30 seconds.
  6. Continue differentiation in 70% alcohol until the grey matter is clear and white matter sharply defined.
  7. Check microscopically.  Repeat the differentiation if necessary starting at step 5.
  8. When differentiation is complete, place in distilled water.
  9. When all slides have been collected in distilled water, add fresh distilled water.
  10. Counterstain in (Cresyl Violet Acetate),Working solution for 6 minutes.
    1. To prepare working solution add 15 drops of Acetic Acid, 10%  to 100ml of
      Cresyl Violet Acetate 0.1% just before use. Filter.
  11. Rinse in 2 changes of 95% alcohol.
  12. Continue the dehydration through two changes of absolute ethyl alcohol and xylene, two changes each, for 2 minutes.
  13. Mount with resinous medium.


Stain Results:

Myelin, including phospholipids

Blue to Green cells

Cells and cell products

Pink to violet

NOTE:  The Luxol Fast Blue procedure works well when combined with other procedures such as the Bodian Method.
