Mouse IL-1ra/IL-1F3 Antibody Summary

Species Reactivity
Mouse
Specificity
Detects mouse IL-1ra/IL-1F3 in ELISAs and Western blots. In sandwich ELISAs, approximately 45% cross-reactivity with recombinant rat IL‑1ra/IL‑1F3 and less than 1% cross-reactivity with recombinant human IL‑1ra/IL‑1F3, recombinant porcine IL‑1ra/IL‑1F3, and recombinant equine IL‑1ra/IL‑1F3 is observed.
Source
Polyclonal Goat IgG
Purification
Antigen Affinity-purified
Immunogen
E. coli-derived recombinant mouse IL‑1ra/IL-1F3
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.
Label
Unconjugated

Use in combination with:

Detection Reagent: Mouse IL‑1ra/IL‑1F3 Biotinylated Antibody (Catalog # BAF480)

Standard: Recombinant Mouse IL-1ra/IL-1F3 Protein (Catalog # 480-RM)

Neutralization
Measured by its ability to neutralize IL‑1ra/IL‑1F3 inhibition of IL‑1 alpha /IL‑1F1-dependent 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 1-5 µg/mL in the presence of 150 ng/mL Recombinant Mouse IL‑1ra/IL‑1F3, 50 pg/mL Recombinant Human IL‑1 alpha /IL‑1F1.

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.

IL‑1ra/IL‑1F3 Inhibition of IL‑1 alpha /IL‑1F1-dependent Cell Proliferation and Neutralization by Mouse IL‑1ra/IL‑1F3 Antibody. Recombinant Mouse IL-1ra/IL-1F3 (Catalog # 480-RM) inhibits Recombinant Human IL-1a/IL-1F1 (Catalog # 200-LA) induced proliferation in the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human IL-1a/IL-1F1 (50 pg/mL) activity elicited by Recombinant Mouse IL-1ra/IL-1F3 (150 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL-1ra/IL-1F3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-480-NA). The ND50 is typically 1-5 µg/mL.

Background: IL-1ra/IL-1F3

IL-1ra was originally isolated from the urine of patients with monocytic leukemia and has also been purified from adherent monocytes. The naturally-occurring, fully glycosylated form has an apparent molecular weight of about 25,000 Daltons. The protein shows 26% amino acid homology to IL-1 beta and 19% homology to IL-1 alpha. It will compete with either factor for receptor binding, but does not interact with either one. Human IL-1ra will bind to both types of IL-1 receptor (I and II) on human cells. In mouse, IL-1 RII does not bind IL-1ra. The recombinant, non-glycosylated form of IL-1ra blocks binding of IL-1 to its receptor equally as well as the naturally-occurring, glycosylated form. The IL-1ra has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. Pre-clinical and clinical studies were done to test possible therapeutic applications for IL-1ra in the treatment of sepsis, rheumatoid arthritis and chronic myelogenous leukemia.
