Decontamination of Ethidium Bromide Solutions

1. Add 1 g of powdered activated charcoal for each 1 L of solution.

2. Store the solution for 1 hour at room temperature, shaking it intermittently.

3. Filter the solution through a Whatman No. 1 filter, and discard the filtrate (and filter) as EtBr solid waste.

4. Contact the Physical Plant for waste disposal.  Fill out the appropriate forms.

Warning:   Phenol is an extremely caustic chemical which will cause severe burns.  Exposure may be through rapid absorption of tissue or through inhalation.  All work with phenol must be conducted under the fume hood.  Protective clothing will be a lab coat, apron, gloves, and goggles. In the event of an exposure, rinse the affected area immediately with running water for at least 10 minutes.

Recipe:
Only redistilled and buffered phenol are used for nucleic acid extractions since the oxidation products of phenol may damage the DNA.
1. Remove distilled phenol from the freezer and allow to warm to room temperature.
2. Melt crystals in 65°C waterbath.  Do not place the hot bottle on a cool counter, as it may result in the bottle fracturing.
3. Add 0.1g of 8-hydroxyquinoline to a 250 ml dark bottle with stir bar.
 The 8-hydroxyquinoline acts as an antioxidant and will turn the phenol yellow.
4. Avoid any splashing and gently pour in 100 ml of melted phenol.
5. Add 100 ml of 1M Tris-HCl, pH 8.  Stir gently for 5 minutes.
6. Allow phases to separate for 5 minutes.
7. Gently decant the aqueous (top) phase into a waste container.
8. Repeat steps 5 to 7.
9. Add 100 ml of 0.1M Tris-HCl, pH 8.  Repeat two more equilibration runs with 0.1M Tris-HCl until the pH of the aqueous phase is 8.
10. Dispose after 2 months.  Before each use, ensure that the pH>7.  If pH<7, repeat steps 5 to 9.
