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

Species Reactivity

Mouse

Specificity

Detects mouse IL-1ra/IL-1F3 in direct ELISAs and Western blots. In Western blots, approximately 30%-50% cross-reactivity with recombinant equine IL-1ra and recombinant human (rh) IL-1ra is observed. Less than 5% cross-reactivity with recombinant mouse (rm) IL-1b, rmIL-18, rmIL-36Ra, rmIL-36a, rmIL-36b, rmIL-1F10, rhIL-36, rhIL-1F7, or recombinant porcine IL-1ra, or recombinant rat IL-1ra is observed.

Detection of Mouse IL‑1ra/IL‑1F3 by Western Blot. Western blot shows lysates of RAW 264.7 mouse monocyte/macrophage cell line treated with 1 µg/mL LPS for 24 hours. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse IL-1ra/IL-1F3 Monoclonal Antibody (Catalog # MAB4801) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for IL-1ra/IL-1F3 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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 kDa. 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.
