Figure 2: Poly(I:C) . K (TLRGRADE®) (synthetic) (Prod. No.
ALX-746-021) induces cytokine release in mouse
in vivo.
Method: Poly(I:C) was injected i.v. and plasma levels of IFN α/β were determined 2 hours later by cytokine ELISA.
Figure 1: Poly(I:C) . K (TLRGRADE®) (synthetic) (Prod. No.
ALX-746-021) induces cytokine release in murine BM-derived macrophages.
Method: Poly(I:C) was added to bone marrow-derived murine macrophages in a 96-well plate at the indicated concentrations, cell supernatants were harvested after 24 hours and IFN α/β levels analyzed by cytokine ELISA.
