Scientific Data Images for Human IL-1 beta/IL-1F2 Antibody

Detection of Human and Mouse IL-1 beta/IL-1F2 antibody by Western Blot.

Detection of Human and Mouse IL‑1 beta/IL‑1F2 by Western Blot.

Western blot shows lysates of THP-1 human acute monocytic leukemia cell line untreated (-) or treated (+) with PMA and LPS and RAW 264.7 mouse monocyte/macrophage cell line untreated (-) or treated (+) with LPS. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human IL-1 beta/IL-1F2 Polyclonal Antibody (Catalog # AB-201-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IL-1 beta/IL-1F2 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
IL-1 beta/IL-1F2 antibody in Human Peripheral Blood Mononuclear Cells by Immunocytochemistry (ICC).

IL‑1 beta/IL‑1F2 in Human Peripheral Blood Mononuclear Cells.

IL-1 beta/IL-1F2 was detected in immersion fixed human peripheral blood mononuclear cells using Goat Anti-Human IL-1 beta/IL-1F2 Polyclonal Antibody (Catalog # AB-201-NA) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasmic. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.
Cell Proliferation Induced by IL‑1 beta/IL‑1F2 and Neutral-ization by Human IL‑1 beta/ IL‑1F2 Antibody.

Cell Proliferation Induced by IL‑1 beta/IL‑1F2 and Neutral-ization by Human IL‑1 beta/ IL‑1F2 Antibody.

Recombinant Human IL-1 beta/IL-1F2 (Catalog # 201-LB) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-1 beta/ IL-1F2 (50 pg/mL) is neutral-ized (green line) by increasing concentrations of Goat Anti-Human IL-1 beta/IL-1F2 Poly-clonal Antibody (Catalog # AB-201-NA). The ND50 is typically 0.05-0.1 µg/mL.

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, IL1B), 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. Intracellular cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. The 17 kDa molecular weight 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. IL-1 beta functions in a central role in immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, and GH/IGF-I physiology. IL-1 beta dysregulation is implicated in many pathological conditions including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulin-dependent diabetes mellitus, atherosclerosis, neuronal injury, and aging-related diseases.
