背景 | IL-23 p19 (Interleukin 23 p19; also IL-23 alpha) is an 18-20 kDa (estimated) member of the IL-6 superfamily of molecules. It is disulfide-bonded to p40 to form IL-23. IL-23 is secreted by immune-related cell types such as keratinocytes, dendritic cells, macrophages, microglia and monocytes, often following TLR stimulation. It appears to drive Th17 cell development by inhibiting T-bet and FoxP3 production, and to reduce IL-12-mediated IFN-gamma production by CD4+, CD8+ and NK cells. Based on human, mature feline IL-23 p19 is 160 amino acids (aa) in length. It is a alpha -helical molecule that utilizes Cys80 to form an interchain disulfide bond with IL-12 p40. IL-23 p19 does not appear to be released unless dimerized to p40. There are no potential N-linked glycosylation sites on p19. Mature feline IL-23 p19 (aa 26-185) shares 87% aa identity with human IL-23 p19. |

Detection of Human IL‑23 p19 by Western Blot. Western blot shows lysates of Hs 294T human melanoma cell line. PVDF Membrane was probed with 1 µg/mL of Feline IL‑23 p19 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6238) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for IL‑23 p19 at approximately 27 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8. |
