GMP-grade Recombinant Human
IL‑1 beta /IL‑1F2 (Catalog # 201-GMP) stimulates proliferation of the D10.G4.1 mouse helper T cell line. The ED50 for this effect is
1 μg/lane of GMP-grade Recombinant Human IL‑1 beta /IL‑1F2 (Catalog # 201-GMP) was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing a single band at 17 kDa.
ESI analysis of GMP-grade Recombinant Human IL‑1 beta /IL‑1F2 (Catalog # 201-GMP). The labeled peaks at 17376 Da and 17305 Da correspond to the calculated molecular masses, 17377 Da (aa 117-269) and 17306 Da (aa 118-269), respectively.
Background: IL-1 beta/IL-1F2
IL-1 is a name that designates two pleiotropic cytokines, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 21% amino acid (aa) identity in human. Both proteins are produced by a wide variety of cells in response to inflammatory agents, infections, or microbial endotoxins. While IL-1 alpha and IL-1 beta are regulated independently, they bind to the same receptor and exert identical biological effects. IL-1 RI binds directly to IL-1 alpha or IL-1 beta and then associates with IL-1 R accessory protein (IL-1 R3/IL-1 R AcP) to form a high-affinity receptor complex that is competent for signal transduction. IL-1 RII has high affinity for IL-1 beta but functions as a decoy receptor and negative regulator of IL-1 beta activity. IL-1ra functions as a competitive antagonist by preventing IL-1 alpha and IL-1 beta from interacting with IL-1 RI (1-4). The human IL-1 beta cDNA encodes a 269 aa precursor. A 116 aa propeptide is cleaved intracellularly by the cysteine protease IL-1 beta -converting enzyme (Caspase-1/ICE) to generate the active cytokine (5-7). The 17 kDa mature human IL-1 beta shares 96% aa sequence identity with rhesus and 67%-78% with canine, cotton rat, equine, feline, mouse, porcine, and rat IL-1 beta.
