Poly (I:C), a synthetic double-stranded RNA (dsRNA) analog, is an immunostimulant that acts as the most potent interferon (IFN) inducer. Toll-like receptor- 3 (TLR3) agonist[1]. Its average molecular weight is between 1.5-8kb.
Mixtures that included the TLR7/8 agonists R848 or CL075, combined with the Poly (I:C), yield 3-d mature dendritic cells [2].
Commonly used to stimulate immune system activation in vivo. Also promotes maturation of hPSC-derived cardiomyocytes[3].?
