STING agonist 4 is an amidobenzimidazole (ABZI)-based compound that functions as a STING agonist with Kd of 1.6 nM (binding of endogenous full-length STING, THP-1 cell lysates); caused dose-dependent phosphorylation of IRF3 and STING that was inhibited by the TBK1 inhibitor BX795, induced dose-dependent secretion of IFN-β with EC50 of 3.1 uM in PBMCs (18-fold more potent than cGAMP); promotes production of IFN-γ-induced protein 10 (IP-10), IL-6 and TNFα by a mechanism that is dependent on STING-mediated activation of TBK1; unlike cGAMP and DMXAA, compound 2 efficiently activates STING function while maintaining an open STING confirmation.

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.
