Scientific Data Images for Canine IL-1 beta/IL-1F2 Antibody

Cell Proliferation Induced by IL-1 beta /IL-1F2 and Neutral-ization by Canine IL‑1 beta /IL‑1F2 Antibody.

Recombinant Canine IL-1 beta /IL-1F2 (Catalog # 3747-CL) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Canine IL-1 beta /IL-1F2 (20 pg/mL) is neutralized (green line) by increasing concentrations of Sheep Anti-Canine IL-1 beta /IL-1F2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF37471). The ND₅₀ is typically 3-18 ng/mL.

Background: IL-1 beta/IL-1F2

IL-1 is a name that designates two pleiotropic cytokines, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 22% amino acid (aa) identity in dog. Both proteins are produced by a wide variety of cells in response to inflammatory agents, infections, or microbial endotoxins. While IL-1 alpha and IL-1 beta are regulated independently, they bind to the same receptor and exert identical biological effects. IL‑1 RI binds directly to IL-1 alpha or IL-1 beta and then associates with IL-1 R accessory protein (IL-1 R3/IL-1 R AcP) to form a high-affinity receptor complex that is competent for signal transduction. IL-1 RII has high affinity for IL-1 beta but functions as a decoy receptor and negative regulator of IL-1 beta activity. IL-1ra functions as a competitive antagonist by preventing IL-1 alpha and IL-1 beta from interacting with IL-1 RI (1 - 4). The canine IL-1 beta cDNA encodes a 266 aa precursor. A 114 aa propeptide is cleaved intracellularly by the cysteine protease IL-1 beta -converting enzyme (Caspase-1/ICE) to generate the active cytokine (5, 6). The 17 kDa mature canine IL-1 beta shares 68-78% aa sequence identity with cotton rat, equine, feline, human, mouse, porcine, rat, and rhesus macaque IL-1 beta.
