Product Description
Interleukin 1 alpha (IL-1 alpha ), IL-1 beta, and IL-1 receptor antagonist (IL-1ra) are members of the IL-1 family. IL-1 alpha and IL-1 beta are agonists that bind the functional IL-1 receptor I (IL-1 RI), which then recruits the IL-1 receptor accessory protein (IL-1 R AcP/IL-1 R3) and initiates signal transduction pathways that include the NF-kappa B. JNK/AP-1, and p38 MAP kinase pathways. Both IL-1 alpha and IL-1 beta also bind the non-signaling IL-1 RII that functions as a decoy receptor. IL-1ra is a receptor antagonist that binds both IL-1 RI and II with equal affinity as the IL-1 alpha and beta. Binding of IL-1ra to IL-1 RI does not initiate signal transduction pathways. IL-1 alpha and beta are pro-inflammatory cytokines that play an important role in host defense. The imbalance between IL-1 ( alpha and beta ) and IL-1ra can influence the development of various pathologic conditions associated with chronic inflammation and tissue destruction. Pre-clinical and clinical studies have indicated that IL-1ra may have therapeutic potential for the treatment of sepsis, rheumatoid arthritis and chronic myelogenous leukemia.

Formulation
Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.
Shipping and Storage
The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
Cautions
1. Avoid repeated freeze-thaw cycles.
2. For your safety and health, please wear lab coats and disposable gloves for operation.
3. For research use only!
