Ordering Information

Biological Activity

Tert-butylhydroquinone (TBHQ) is an antioxidant compound and activator of the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Activation of Nrf2 by TBHQ promotes the nuclear translocation of Nrf2, inducing the expression of antioxidant response element (ARE)-driven cytoprotective genes. This pathway activation suppresses intracellular reactive oxygen species accumulation and lipid peroxidation, ultimately protecting cells against oxidative stress-induced cytotoxicity. [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).
