Biological activity

Ligand of TLR3 and RLR.

Properties

  • RGIC50 generates a Th1 immune response with a particular activation of CD8+ positive T cells.
  • RGIC50 strongly activates dendritic cells and monocytes.
  • RGIC50 has a very well defined chemical structure, length and molecular weight, and a good solubility.
  • RGIC50 is stable in body fluids up to seven days.
  • RGIC50 is less toxic than poly(I:C) and has a much higher LD50 than poly(I:C).

Development stage

  • RGIC50 has completed all pre-clinical development stages including GMP manufacturing.
  • RGIC50 is commercially available to scientists performing vaccination studies in vivo (RIBOXXOL CLINIgrade®).
  • GMP TLR3 ligand RGIC50 is available for pharmaceutical companies or public institutions performing Phase I to III clinical studies in cancer or virus diseases (immunotherapy, immunooncology).
