Ordering Information

Biological Activity

Fatostatin is a diarylthiazole derivative that acts as a specific inhibitor of sterol regulatory element-binding protein (SREBP) activation. By directly binding to SREBP cleavage-activating protein (SCAP), Fatostatin blocks the translocation of SREBPs from the endoplasmic reticulum to the Golgi apparatus. Inhibition of the SREBP signaling pathway disrupts lipid biosynthesis, leading to suppressed cell proliferation and enhanced apoptosis in cancer cells. [1]

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).
