Description

• Description: The 364/3B3-14 antibody reacts with human interleukin-1alpha
• Applications Reported: The 364/3B3-14 antibody has been reported for intracellular staining for flow cytometric analysis
• Applications Tested: This 364/3B3-14 antibody has been tested intracellular staining and flow cytometric analysis of stimulated human blood cells
• This can be used at less than or equal to 1 μg per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
• Purity: Greater than 90%, as determined by SDS-PAGE
• Aggregation: Less than 10%, as determined by HPLC
• Filtration: 0.2 μm post-manufacturing filtered
• 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.
