Ordering Information

Biological Activity

Tauroursodeoxycholic acid (TUDCA) is an endogenous bile acid derivative that functions as a mitochondrial stabilizer, chemical chaperone, and anti-apoptotic agent. It inhibits mitochondrial membrane depolarization and cytochrome c release, suppressing caspase activation and downstream apoptotic pathways. Additionally, TUDCA attenuates endoplasmic reticulum (ER) stress by suppressing unfolded protein response signaling, thereby maintaining cellular homeostasis in various disease models. [1][2]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
