Double-stranded DNAs

Polyinosinic-polycytidylic acid (Poly(I:C)) is a synthetic analog of double-stranded RNA and an agonist of toll-like receptor 3 (TLR3) and retinoic acid inducible gene I (RIG-I)-like receptors (RIG-I and MDA5). Polyinosinic-polycytidylic acid can be used as a vaccine adjuvant to enhance innate and adaptive immune responses, and to alter the tumor microenvironment. Polyinosinic-polycytidylic acid can directly trigger cancer cells to undergo apoptosis.

ISD sodium is an interferon-stimulatory DNA, a 45 bp non-CpG double-stranded oligonucleotide derived from the genome of Listeria monocytogenes. ISD sodium potently induces type I interferon production via the cGAS‑STING‑TBK1‑IRF3 pathway.

dsVACV-70mer (sodium) is a 70 bp double-stranded oligonucleotide containing viral DNA motifs derived from vaccinia virus DNA. dsVACV-70mer (sodium) has potently induces IFN-β via a STING-dependent manner.

HSV-60mer sodium is a 60 bp double-stranded DNA oligonucleotide derived from the HSV-1 genome, and also an IFNβ inducer. HSV-60mer sodium colocalizes with endogenous cytoplasmic IFI16 in immune cells. HSV-60mer sodium activates the transcription factors IRF3 and NF-κB, induces the production of proinflammatory cytokines, and inhibits HSV-1 replication in immune cells. HSV-60mer sodium can be used in studies related to herpes simplex virus type 1 infection.
