- BIOLOGICAL ACTIVITY: Determined by its ability to inhibit the IL-1α stimulation of murine D10S cell. The expected ED50 is 20-40 ng/ml in the presence of 50 pg/ml of IL-1alpha.
Properties
- PURITY: ≥ 98% by SDS-PAGE gel and HPLC analyses.
- PHYSICAL STATE: Lyophilized
- STORAGE CONDITIONS: The recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background
- Interleukin-1 receptor antagonist (IL-1RA) is a naturally-occurring, inflammatory-inhibitor protein. It inhibits the activity of IL-1α and IL-1β by competitively blocking their binding to type I and type II receptors. IL-1RA is produced by corneal epithelial cells, monocytes, neutrophils, macrophages, and fibroblasts. Therapeutically, IL-1RA may help in the treatment of sepsis, cachexia, rheumatoid arthritis, chronic myelogenous leukemia, asthma, psoriasis, and inflammatory bowel disease. Recombinant Human IL-1RA is a 17.2 kDa protein consisting of 153 amino acid residues.
