Applications
  •  
    Recommended
    Concentration
    Sample
  • Neutralization
    Measured by its ability to neutralize IL‑1 beta /IL‑1F2-induced proliferation in the D10.G4.1 mouse helper T cell line. Symons, J.A. et al. (1987) in Lymphokines and Interferons, aThe Neutralization Dose (ND50) is typically 2-10 μg/mL in the presence of 100 pg/mL Recombinant Equine IL‑1 beta /IL‑1F2.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Example
Cell Proliferation Induced by IL‑1 beta /IL‑1F2 and Neutral­ization by Equine IL‑1 beta /IL‑1F2 Antibody. Recombinant Equine IL‑1 beta /IL‑1F2 induces proliferation in the D10.G4.1 mouse helper T cell line in the presence of concanavalin A (1.25 μg/mL) in a dose-depend­ent manner (orange line), as measured by the Resazurin (Catalog # AR002). Under these conditions, proliferation elicited by IL‑1 beta /IL‑1F2 is neutralized (green line) by increasing concen­trations of Mouse Anti-Equine IL‑1 beta /IL‑1F2 Monoclonal Antibody (Catalog # MAB8049). The ND50 is typically 2-10 μg/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 27% amino acid (aa) identity in equine. 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 equine IL-1 beta cDNA encodes a 268 aa precursor. A 115 aa propeptide is cleaved intracellularly by the cysteine protease IL-1 beta -converting enzyme (Caspase-1/ICE) to generate the active cytokine (5-7). An alternatively spliced form of equine IL-1 beta has a deletion which encompasses the Caspase-1 cleavage site and potentially results in a membrane-associated form (8). The 17 kDa mature equine IL-1 beta shares 65%-75% aa sequence identity with canine, cotton rat, feline, human, mouse, porcine, rat, and rhesus IL-1 beta.
