Interleukin 1 receptor antagonist (IL1RN, IL1F3, IL1RA, IRAP) is a protein that is produced in at least two forms, one that is intracellular and one that is secreted. This assay is for the secreted version. IL-1RA is secreted by various cell types including epithelial cells, monocytes, and adipocytes. It binds to the IL-1 receptor thus preventing signaling by both IL-1α and IL-1β cytokines. IL-1RA is a biomarker for osteoporosis, gastric cancers, and rheumatoid arthritis.

Application Areas

IL-1RA assays are available for human and NHP samples in both single and multiplex formats.
Select these or create a custom multiplex assay including IL-1RA with the U-PLEX Assay Designer.
