Description

Goat Polyclonal Antibody

In direct ELISA, approximately 50% cross-reactivity with recombinant canine IL-23p19, less then 25% cross-reactivity with recombinant feline IL-23p19, less than 5% cross-reactivity with recombinant mouse IL-23p19, recombinant human IL-12p40, and recombinant rat IL-23p40 is observed. Reconstitute at 0.2 mg/mL in sterile PBS. Endoxin level is <0.10 EU per 1 μg of the antibody by the LAL method.

IL-23 is a heterodimeric cytokine composed of the p40 subunit of IL-12 disulfide-linked with a protein p19. p19, like p35 of IL-12, is biologically inactive by itself. IL-23 interacts with IL-12Rbeta1 and an additional, novel beta2-like receptor subunit with STAT4 binding domain, termed IL-23R. IL-23 is secreted by activated mouse and human dendritic cells. Biological activities of mouse IL-23 are distinct from those of mouse IL-12. Mouse IL-23 was found not to induce significant amounts of IFN-γ. Mouse IL-23 does induce strong proliferation of memory T cells (but not naive T cells), whereas IL-12 has no effect on memory cells. Additionally, mouse IL-23 (but not IL-12) can activate mouse memory T cells to produce the proinflammatory cytokine IL-17. Human IL-23 has biological properties which are less distinct from human IL-12; human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN-γ production by naive and memory T cells, as compared to IL-12.
