Cyclic diguanylate monophosphate - STING agonist

Cyclic diguanylate monophosphate (c-di-GMP) is is a cyclic dinucleotide (CDN) produced by bacteria in which it acts as a prevalent intracellular messenger. It controls motility, biofilm formation and bacterial pathogenicity.

CDNs are a relatively new class of adjuvants that have been shown to increase vaccine potency [1]. CDNs activate innate immunity by directly binding the endoplasmic reticulum-resident receptor STING (stimulator of interferon genes), activating a signaling pathway that induces the expression of interferon-β (IFN-β) and also nuclear factor-κB (NF-κB) dependent inflammatory cytokines [2, 3].

Recent studies have also demonstrated that c-di-GMP exerts strong adjuvant activities when delivered by the mucosal route [4, 5]. c-di-GMP has been reported to elicit a balanced Th1/Th2 profile and Th17 response, which is crucial against intracellular pathogens [6].

c-di-GMP VacciGrade™ is a preclinical grade preparation of the cyclic dinucleotide c-di-GMP.


c-di-GMP VacciGrade™ is for research use only, not for use in humans.

THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). IRF induction was determined by measuring the relative light units (RLUs) in a luminometer using QUANTI‑Luc™, a Lucia luciferase detection reagent.


THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). NF‑kB induction was determined using QUANTI‑Blue™, a SEAP detection reagent, and by reading the optical density (OD) at 655 nm. Non-induced cells (NI) have been included as a negative control.
