Product Specific Information

Description: The ALF-161 antibody reacts with mouse interleukin-1alpha (IL-1alpha). Mouse IL-1alpha, also called Lymphocyte Activating Factor (LAF), Endogenous Pyrogen (EP), Leukocyte Endogenous Mediator (LEM), and Mononuclear Cell Factor (MCF), is a 17 kDa factor produced by a wide variety of cells, including macrophages, dendritic cells, T and B cells. IL-1alpha is mostly cell-associated, with 23% amino acid homology with IL-1beta. The immune regulatory role of IL-1alpha is exerted on a wide range of cells including lymphocytes, epithelial cells and fibroblasts. In vivo, it induces hypotension, fever, and acute phase response.

Applications Reported:The ALF-161 antibody has been reported for use in ELISA capture, ELISPOT capture, neutralization, and intracellular staining for flow cytometry.

Applications Tested: The Functional Grade Purified ALF-161 antibody has been tested by LAL assay to verify low endotoxin levels, by ELISA, and in bioassay for neutralization of mouse IL-1 alpha bioactivity.

The ALF-161 antibody at 0.031 µg/mL has been found to inhibit by 50% the biological effects of 4.0 ng/mL mouse IL-1 alpha in a D10 cell proliferation assay. Detailed information and protocols about cytokine bioassays and in vitro cytokine neutralization using antibodies can be found in the BestProtocols® section.

The ALF-161 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse interleukin-1 alpha (IL-1 alpha) in combination with the biotin anti-mouse Interleukin-1 alpha (IL-1 alpha) polyclonal (13-7111) antibody for detection and recombinant mouse IL-1 alpha (14-8011) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 1-4 µg/mL. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 1000pg/mL - 8pg/mL should be included in each ELISA plate.

Storage and handling: Use in a sterile environment.

Filtration: 0.2 µm post-manufacturing filtered.

Purity: Greater than 90%, as determined by SDS-PAGE.

Endotoxin Level:Less than 0.001 ng/µg antibody, as determined by LAL assay.

Aggregation:Less than 10%, as determined by HPLC.

Target Information

IL-1 alpha (Interleukin-1 alpha) is a proinflammatory cytokine expressed by monocytes, macrophages, and dendritic cells. IL-1 alpha is coded by the IL1A gene and signals through two receptors, IL-1RI and IL-1RII, both of which are shared with IL-1 beta. IL1A is located on the q arm on chromosome 2 at position 13. IL-1 alpha plays an important role in innate host defense by triggering the production of other proinflammatory cytokines in target cells and initiating acute-phase responses. IL-1 alpha activity can be moderated by IL-1 Receptor Antagonist (IL-1RA), a protein produced by many cell types that blocks receptor binding through competitive inhibition. IL-1 alpha is a pleiotropic cytokine involved in various immune responses, inflammatory processes, and hematopoiesis. Further, IL-1 alpha is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury and induces apoptosis. The IL1A gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. IL1 alpha regulates the activities of NF-kappaB and mitogen-activated protein kinases. IL-1 alpha can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of IL-1 alpha are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis.
