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

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

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

Recombinant Rat IL-1 beta/IL-1F2 (Catalog # 501-RL) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat IL-1 beta/IL-1F2 (4 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Rat IL-1 beta/IL-1F2 Monoclonal Antibody (Catalog # MAB501). The ND50 is typically 10-30 µg/mL.

Applications for Rat IL-1 beta/IL-1F2 Antibody

Application
Recommended Usage

Immunocytochemistry

8-25 µg/mL
Sample: Immersion fixed rat splenocytes activated with LPS

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, a Practical Approach. Clemens, M. J. et al. (eds): IRL Press. 272. The Neutralization Dose (ND50) is typically 10-30 µg/mL in the presence of 4 ng/mL Recombinant Rat IL‑1 beta/IL‑1F2.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

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 26% amino acid (aa) identity in rat. 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 rat IL-1 beta shares 90% aa sequence identity with cotton rat and mouse 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.
