生物活性

STING-IN-16 is a STING inhibitor with IC50 values of 44 nM (human) and 32 nM (mice) for cellular STING inhibition. STING-IN-16 effectively inhibits the activation of the STING axis in both human and murine cells. STING-IN-16 can restore renal mitochondrial function, suppress reactive oxygen species (ROS) production, and reduce cell apoptosis. STING-IN-16 shows robust anti-inflammatory efiicacy in vivo. STING-IN-16 can be used for the study of autoimmune and autoinflammatory diseases[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.
