PSTC is a potent, selective Nrf2 activator with pEC50 of 7.7 (inducing of NQO1 specific enzyme activity).PSTC induces Nrf2 nuclear translocation, Nrf2-regulated gene expression, and downstream signaling events, including induction of NAD(P)H:NQO1 enzyme activity and heme oxygenase-1 protein expression, in an Nrf2-dependent manner.PSTC does not inhibit IL-1β-induced NF-κB translocation or insulin-induced S6 phosphorylation in human cells.PSTC restores oxidant (tert-butyl hydroperoxide) induced glutathione depletion in vitro and in vivo models of pulmonary oxidative stress.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
