1. Dissolve 150 g trichloroacetic acid in water and make up to 1 000 ml.

2. Dissolve # g of trichloroacetic acid (CCI#CCOOH) in water and make up to # ml

3. Use freshly prepared solutions, because GMP degrades in an 8 % trichloroacetic acid environment at room temperature.

4. Use freshly prepared solutions, because CMP degrades in an # % trichloroacetic acid environment at room temperature

5. Use freshly prepared solutions, because GMP degrades in an # % trichloroacetic acid environment at room temperature

6. Use freshly prepared solutions, because CMP degrades in an 8 % trichloroacetic acid environment at room temperature.

7. Tritiated thymidine incorporation was measured using phenol–chloroform extractions; leucine incorporation was measured in trichloroacetic acid precipitates.

8. Methods:Urinary proteins were precipitated with 3% trichloroacetic acid (TCA) solution and the supernatant fraction was used to reactivate apoCA to catalyze p-nitrophenyl acetate.
