Von Kossa Stain Protocol

The method was originally developed by von Kossa, and underwent several modifications. The stain principle is a precipitation reaction in which silver ions react with phosphate (not calcium) in the presence of acidic material. Photochemical degradation of silver phosphate to silver then occurs under light illumination.

Additional methods need to be employed to confirm the presence of calcium and hydroxyapatite, such as Alizarin Red, which detects calcium deposits.

VON KOSSA Stain Procedure:

1. Sections to water.

2. Place sections in 1% silver nitrate solution under reasonable light for 30-60 minutes.

3. Wash in distilled water.

4. Treat with 3% sodium thiosulphate for 3-5 minutes.

5. Wash in water.

6. Counterstain with van Gieson for 3-5 minutes.

7. Wash in alcohol.

8. Clear .

9. Mount sections

RESULTS:

Mineralised bone black Osteoid red
