Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Auramine O staining of Tuberculosis bacilli[3]
1. Place the slide on a staining rack and stain with Auramine O solution for 20 min
2. Rinse the slide with water and soak it in 0.5% acid alcohol for 3 min
3. Rinse with water and counterstain with 1% KMnO4 solution for 1 min
4. Check the staining effect with an LED microscope with at least 40 fields of view
Note: Tuberculosis bacilli appear as yellow luminescent organisms in a dark field of view
