Biological Activity

Poly(I:C) is a synthetic double-stranded RNA (dsRNA); endosomal Toll-like receptor 3 (TLR3) agonist. It also binds to the cytoplasmic receptors, retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA-5), elicits the secretion of type I interferon (IFN) and pro-inflammatory cytokines. Poly(I:C) is commonly used for immune system activation in vivo. Poly(I:C) also promotes maturation of hPSC-derived cardiomyocytes by modulating early Notch signaling and cardiomyogenic transcriptional programs. Poly(I:C) promotes generation of stable, mature dendritic cells in combination with TLR8 agonist CL 075 (Cat. No. 6142). Transfection into NIT-1 β cells induce β-cell apoptosis. Commonly used to stimulate immune system activation in vivo.
