Description: The human IL-1RA ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of human IL-1RA. The human IL-1RA ELISA is for research use only. Not for diagnostic or therapeutic procedures.
Interleukin 1 receptor antagonist is a protein related to the IL-1 family based on its similarities in amino acid sequence to both IL-1 beta and IL-1 alpha, similarities in gene structure, and collective gene localization. The human gene contains four exons and maps to chromosome 2q13-14.
IL-1 RA binds to the IL-1 receptor and blocks IL-1 action through competitive inhibition. In contrast to IL-1, the binding of IL-1RA does not initiate signaling events. The secretion of IL-1 RA is mediated by a classical signal sequence while neither IL-1alpha nor IL-1beta possess such a sequence. The lack of homology between IL-1 RA and IL-1 alpha or IL-1 beta near the N terminus may provide an explanation for the biosynthetic and functional differences between IL-1 RA and the two IL-1 proteins.
The production of IL-1RA is stimulated by many substances including adherent IgG, cytokines, and bacterial or viral components. IL-1RA is an important natural anti-inflammatory protein that when missing or just available in inadequate amounts plays a key role in several pathological conditions such as rheumatoid arthritis, colitis, osteomyelitis, periostitis and pustulosis.
