  • Highly pure and selective ligand for TLR7 and TLR8
  • Highly cited
R-848 is a selective ligand for Toll-like receptor 7 (TLR7) in mouse and for TLR7 and TLR8 in human. R-848 displays potent antitumor, proinflammatory, and anti-viral properties. R-848 stimulates antibody secretion, cytokine production (e.g. IL-6, IL-12, and IFNg), protection from apoptosis, and CD80 upregulation.
