Negative control for 5′ppp-dsRNA

5’ppp-dsRNA Control is a negative control for 5’ triphosphate double-stranded RNA (5’ppp-dsRNA), a synthetic ligand for the retinoic acid-inducible protein I (RIG-I, also known as Ddx58). RIG-I is a cytoplasmic RNA helicase that belongs to the RIG-I-like receptors (RLRs) family and triggers an antiviral immune response by the activation of type-I interferons (IFN-α and -β) [1]. RIG-I detects viral RNAs that exhibit an uncapped 5’-di/triphosphate end and a short blunt-ended double-strand portion, two essential features facilitating discrimination from self-RNAs [2-4]. 5’ppp-dsRNA Control is a 19 mer blunt-end dsRNA without a 5’triphosphate.

5’ppp-dsRNA Control must be delivered into the cytoplasm, for example by using a transfection agent, such as LyoVec™.


Key features of 5'ppp-dsRNA Control:

  • Negative control for the specific RIG-I specific agonist 5'ppp-dsRNA (it does not contain the 5' triphosphate moiety).
  • Its biological activity has been verified using cellular assays.
  • For your convenience, pre-complexed 5'ppp-dsRNA Control/ LyoVec™ is also available.
