Description: The HNU2319 monoclonal antibody is specific to the p19 subunit of human IL-23, a heterodimeric cytokine made up of two covalently linked subunits, p40 and p19. It is closely related to IL-12, with which it shares the p40 subunit. Dendritic cells and macrophages produce IL-23 in response to TLR2, TLR4, and TLR8 ligands, as well as the beta-glucan receptor Dectin-1. Human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN-gamma production by naive and memory T cells, as compared to IL-12. In contrast, the mouse IL-23 biological activities are more distinctly different than those of mouse IL-12 suggesting the signaling or response elements (receptors) differ between species. The IL-23 receptor is also heterodimeric and shares the IL-12Rbeta1 chain with IL-12, while the IL-23R chain is unique to IL-23. Signaling occurs through the Jak/STAT pathway and results in RORgammat expression, which drives the differentiation of CD4^+ T-cells towards the Th17 phenotype. The monoclonal antibody HNU2319 neutralizes the bioactivity of IL-23 without affecting IL-12. Applications Reported: The monoclonal antibody HNU2319 reacts with the p19 subunit of human IL-23 and inhibits its bioactivity. Applications Tested: The ND50 of HNU2319, as determined by the neutralization of mouse IL-17A induction in balb/c splenocytes by recombit human IL-23, is 0.2-0.4 µg/mL in the presence of 2 ng/mL IL-23.

This antibody is specific to the p19 subunit of IL-23, and will not affect the bioactivity of IL-12. The neutralization dose of this antibody will vary depending on cell type, assay method, and concentration of cytokine. Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay. Storage and handling: Use in a sterile environment. Filtration: 0.2 µm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC. This gene encodes a subunit of a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. This cytokine is required for the T-cell-independent induction of interferon (IFN)-gamma, and is important for the differentiation of both Th1 and Th2 cells. The responses of lymphocytes to this cytokine are mediated by the activator of transcription protein STAT4. Nitric oxide synthase 2A (NOS2A/NOS2) is found to be required for the signaling process of this cytokine in innate immunity.
