Staining (Use 5 Slides)
- Deparaffinize and hydrate to distilled water.
- Stain for all 5 slides in Phioxine B, 0.5% Solution for 30 minutes.
- Remove one slide, rinse in water and 95% alcohol and hold in n-Butyl Alcohol. Rinse the remaining 4 slides quickly in water.
- Stain the remaining 4 slides in Tartrazine Solution and remove at 2,5, 10 and 20 minutes. Each time, rinse in 95% alcohol and hold in n-Butyl Alcohol following removal.
- When all 5 slides are in n-Butyl Alcohol, change to fresh n-Butyl Alcohol for 4 minutes, then clear and mount.
Staining Results
The least acidophilic elements stained in the phloxine control slide lose the red color after 2 minutes in the tartrazine solution. The most acidophilic retain the phloxine after 20 minutes in the tartrazine.
