IL-23 (human) (rec.)

Product description: Protein. Human IL-12p40 peptide (aa 23-328) is fused at the C-terminus to a 18 aa linker peptide (GSTSGSGKPGSGEGSTKG) and to the IL-23p19 peptide (aa 20-189) and fused at the N-terminus to a FLAG®-tag. Source: HEK 293 cells. Endotoxin content: <0.06EU/µg purified protein (LAL test; Lonza). Lyophilized from 0.2µm-filtered solution in PBS. Purity: >90% (SDS-PAGE). Interleukin-23 (IL-23) is a heterodimeric cytokine and a member of the IL-12 family involved in innate and adaptive immunity. It is composed of the IL-12 p40 chain covalently linked to p19, a chain related to the IL-12 p35 subunit. IL-23 signals through the IL-23 receptor complex, which is composed of the IL-12Rbeta1 chain and a gp130-like chain, IL-23R. Triggering of the IL-23 receptor complex leads to the activation of Tyk2, Jak2 and STAT1, 3 and 4. IL-23 induces IFN-gamma production, Th1 cell differentiation, and activation of the antigen-presenting functions of dendritic cells. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and important for tumorigenesis.
