Ames Keta-Diastix test for glucose

1 M NaCl

Procedure

1. Pack the Poly-Prep chromatography column with

2 ml AG 1-X8 resin, 200-400 mesh, formate form.

2. Convert the resin to the OH form by washing it with

10 bed volumes of 1 N NaOh, then with 5 bed vol-
umes of distilled water.

3. Add 1 ml of the glucose sample.

4. Wash with 3 bed volumes of water.

5. Check for the presence of glucose.

6. Elute the glucose with 1 M NaCl.

7. Check for glucose.
