  • Description

  • Cyclic diadenylate monophosphate (c-di-AMP) is an intracellular signaling molecule produced by bacteria. Administration of c-di-AMP can induce a strong immune response in vitro and in vivo. It was recently found that this cyclic dinucleotide induces the production of cytokines, such as type I interferons, through the STING/TBK1/IRF3 pathway. Due to its immunostimulatory properties, this molecule has been investigated as a vaccine adjuvant. Mucosal delivery of c-di-AMP elicits a balanced Th1/Th2 profile and Th17 response2, which is crucial against intracellular pathogens. This adjuvant acts through the recruitment of monocytes and granulocytes, and the maturation of dendritic cells.
  • Preparation of Sterile Stock Solution (2 mg/ml)
  • Add 500 μl endotoxin-free physiological water to the 1 mg c-di-AMP vial to obtain a solution at 2 mg/ml.
    Mix the solution by pipetting up and down.
  • Working Concentration
  • 5-50 μg/mouse
