General description

Sodium tauroursodeoxycholate is a bile salt which is naturally present in the small bowel.


Sodium tauroursodeoxycholate has been used in a study to assess short-term feedback regulation of bile salt uptake in rodent liver. It has also been used in a study to investigate its potential to resolve endoplasmic reticulum (ER) stress in intestinal epithelial cells. It is also used for isolation of membrane proteins including inner mitochondrial membrane proteins.

Bile salt-related, anionic detergent used for isolation of membrane proteins including inner mitochondrial membrane proteins.
