Sugar Preference Test (CAT#: STEM-AE-0011-WXH)

Evaluate the depressive-like behavior of animals and the effect of antidepressant drugs.

1. Raise the mice in a single cage and eat freely.
2. On the first day of the experiment, two bottles of drinking water were placed in each cage.
3. On the second day, switch to a bottle of 1% sucrose water and a bottle of drinking water.
4. On the third day, the positions of the two bottles are exchanged to adapt to the sugar water.
5. On the fourth day, the mice were fasted from food and water.
6. Place a weighed bottle of sugar water and a bottle of drinking water in each cage on the fifth day.
7. On the sixth day, weigh the amount of remaining water. The difference between the two times is the amount of drinking water and sucrose water. Finally, the sugar water preference is sucrose water/(drinking water + sucrose water)*100%.
