    Product Description

    StA-IFN-1 is an inhibitor of the interferon (IFN) induction pathway with an IC50 value of 4.1 µM in a GFP reporter assay for IFN induction similar to TPCA-1 (Item No. 15115), which specifically inhibits the IKKβ component of the IFN induction pathway.1 It does not show inhibitory activity in a GFP reporter assay for IFN signaling in which ruxolitinib (Item No. 11609), which is specific for the IFN signaling component JAK1, is active. StA-IFN-1 reduces the levels of IFN-β, but not ISG MxA, mRNA, suggesting that it is selective for the IFN induction pathway and not the IFN signaling pathway.

    WARNING This product is not for human or veterinary use.
