Biological Activity

Synthetic double-stranded RNA (dsRNA); Toll-like receptor 3 (TLR3) agonist. Aids generation of stable, mature dendritic cells in combination with TLR8 agonist CL 075. Transfection into NIT-1 β cells induces β-cell apoptosis. Commonly used to stimulate immune system activation in vivo. Also promotes maturation of hPSC-derived cardiomyocytes.

To prevent denaturation, this product should be reconstituted in solutions with physiological salt concentrations.
