    Description

    STING agonist-12 (Compound 53) is a potent, orally active human STING activator with an EC50 of 185 nM[1].

    IC50 & Target

    EC50: 185 nM (STING)[1]
    In Vitro

    STING agonist-12 (Compound 53) (10 μM) shows excellent pan-polymorph activity across the panel of STING proteins (92%, 107% and 92% against R232, H232 and HAQ, respectively) in HEK293T cells[1].
    STING agonist-12 is not active at mouse STING[1].

    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.
