Detects cotton rat IL‑1 beta /IL‑1F2 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross‑reactivity with recombinant human IL-1 beta and recombinant mouse IL-1 beta is observed, and 10% cross‑reactivity with recombinant rat IL-1 beta and recombinant porcine IL-1 beta is observed.

Recombinant Cotton Rat IL‑1 beta /IL‑1F2 (Catalog # 1009-CL)
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 0.4-1.2 µg/mL in the presence of 2 ng/mL Recombinant Cotton Rat IL‑1 beta /IL‑1F2 and 1.25 µg/mL concanavalin A.
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.
Cell Proliferation Induced by IL‑1 beta /IL‑1F2 and Neutralization by Cotton Rat IL‑1 beta / IL‑1F2 Antibody. Recombinant Cotton Rat IL‑1 beta /IL‑1F2 (Catalog # 1009‑CL) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose‑dependent manner (orange line). Proliferation elicited by Recombinant Cotton Rat IL‑1 beta /IL‑1F2 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat IL‑1 beta / IL‑1F2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1009). The ND50 is typically 0.4-1.2 µg/mL in the presence of concanavalin A (1.25 µg/mL).

Background: IL-1 beta/IL-1F2
IL-1 beta (Interleukin-1 beta) is produced in response to inflammatory agents, infections, or microbial endotoxins. It plays 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. Intracellular cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. IL-1 beta binds to IL-1 RI and IL-1 RII. The IL-1 receptor accessory protein (IL-1 RAcP) associates with IL-1 RI and is required for IL-1 RI signal transduction, and IL-1ra is a secreted molecule that functions as a competitive inhibitor of IL-1 bioactivity.
