Detection of Human 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 200 nM PMA for 24 hours and 10 µg/mL LPS for 3 hours. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB601R) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). 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.

Detection of IL‑1 beta /IL‑1F2 in THP‑1 Human Cell Line.

IL‑1 beta /IL‑1F2 was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line using Mouse Anti-Human IL‑1 beta /IL‑1F2 Monoclonal Antibody (Catalog # MAB601R) at 8 µg/ml for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to the cytoplasm of THP-1 cells treated with 200nM PMA for 24 hours then 10ug/mL LPS for 24 hours.

IL-1 beta /IL-1F2 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) treated with 1 µg/mL LPS and 3 µM monensin for 24 hours using Mouse Anti-Human IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB601R) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human IL‑1 beta /IL‑1F2 by Simple Western^TM.

Simple Western lane view shows lysates of THP‑1 human acute monocytic leukemia cell line untreated (-) or treated (+) with 200 nM PMA for 200 nM and 10 μg/mL LPS for 3 hours, loaded at 0.2 mg/mL. A specific band was detected for IL‑1 beta /IL‑1F2 at approximately 37 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human IL‑1 beta /IL‑1F2 Monoclonal Antibody (Catalog # MAB601R). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Cell Proliferation Induced by IL-1 beta /IL-1F2 and Neutralization by Human IL-1 beta /IL-1F2 Antibody.

Recombinant HumanIL-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) as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human IL-1 beta /IL-1F2 (50 pg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB601R). The ND₅₀ is typically 50-200 ng/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.
