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.
