Background

Interleukin-1β ( IL-1β) is a potent stimulator of bone resorption whose gene is mapped to 2q14, and has been implicated in the pathogenesis of high bone turnover and osteoporosis. IL-1β, a prominent microglia-derived cytokine, caused oligodendrocyte death in coculture with astrocytes and microglia, but not in pure culture of oligodendrocytes alone1. It also can cause nuclear export of a specific NCOR corepressor complex, resulting in derepression of a specific subset of nuclear factor-kappa-B (NFKB)-regulated genes2. Furthermore, Microenvironmental IL-1β and, to a lesser extent, IL-1a are required for in vivo angiogenesis and invasiveness of different tumor cells3. Additional, the cooperation of IL-1β and PDGFB induces contractile-to-synthetic phenotype modulation of human aortic smooth muscle cells in culture4. Moreover, the association with disease may be explained by the biologic properties of IL-1β, which is an important proinflammatory cytokine and a powerful inhibitor of gastric acid secretion5.

Principle

The ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. The target specific antibodies are precoated onto 96-well plates. The target from the sample is bound to the microwell. The biotinylated target specific detection antibodies are added to the microwells and followed by washing with the PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with the PBS or TBS buffer. TMB, the HRP (horseradish peroxidase) substrate, is used to visualize color change resulting from the HRP enzymatic reaction. TMB is catalyzed by HRP to produce the blue color. The color changes into yellow after the acidic stop solution is added. The density of the yellow color is proportional to the target amount from the sample captured in the microwells.
