STING agonist negative control

c-di-GMP Control, also known as 5'-pGpG, is a linear dinucleotide analog that can be obtained after hydrolysis of cyclic diguanylate monophosphate (c-di-GMP) by phosphodiesterases [1]. c-di-GMP is a cyclic dinucleotide (CDN) produced in bacteria in which it functions as a second messenger. c-di-GMP is involved in complex biological processes, such as biofilm formation, virulence and photosynthesis.

CDNs including c-di-GMP bind the cytosolic DNA sensor STING (stimulator of interferon genes) and induce the production of type I interferons (IFNs). Due to its linear conformation, 5'-pGpG is intended to serve as a negative control for c-di-GMP in type I IFN induction assays. The importance of dinucleotide conformation has been well established in bacteria, where RNA regulatory riboswitches are able to discriminate between biologically active CDNs and their corresponding linear dinucleotides [2-4].
