    Description

    STING-IN-2 (C-170) is a potent and covalent STING inhibitor. STING-IN-2 efficiently inhibits both mouse STING (mmSTING) and human STING (hsSTING). STING-IN-2 can be used for autoinflammatory disease research[1].

    In Vitro

    THP-1 cells are pretreated with STING-IN-2 (C-170; 0.5 μM) and stimulated with cGAMP. STING-IN-2 (C-170) treatment decreases the IFNB1 and TNF mRNA levels, and also reduces the p-TBK1 levels[1].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
