Scientific Data Images for Mouse IL-1 beta/IL-1F2 Antibody (30311R)

IL‑1 beta /IL‑1F2 in Mouse Splenocytes.

IL-1 beta /IL-1F2 was detected in immersion fixed mouse splenocytes treated with LPS using Recombinant Rat Anti-Mouse IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB401R) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Cell Proliferation Induced by IL-1 beta /IL-1F2 and Neutralization by Mouse IL-1 beta /IL-1F2 Antibody.

Recombinant Mouse IL-1 beta /IL-1F2 (Catalog # 401-ML) stimulates proliferation in 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 Mouse IL-1 beta /IL-1F2 (50 pg/mL) is neutralized (green line) by increasing concentrations of the Recombinant Rat Anti-Mouse IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB401R). The ND₅₀ is typically 1-5 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, IL1B), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 17% amino acid (aa) identity in mouse. 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. Intracellular cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. The 17 kDa molecular weight mature mouse IL-1 beta shares 90% aa sequence identity with cotton rat and rat and 67%-78% with canine, equine, feline, human, porcine, and rhesus macaque IL-1 beta. IL-1 beta functions in a central role in immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, and GH/IGF-I physiology. IL-1 beta dysregulation is implicated in many pathological conditions including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulin-dependent diabetes mellitus, atherosclerosis, neuronal injury, and aging-related diseases.
