Description

Interleukin-33 (IL-33), also known as NF-HEV and DVS 27, is a 30 kDa pro-inflammatory protein. Human IL-33 is synthesized as a 270 amino acid molecule with an N-terminal nuclear localization signal, a helix-turn-helix motif, and a C-terminal region with structural homology to IL-1 family cytokines.  IL-33 exerts multiple effects on immune system function. It acts on Th2 cells, basophils, and mast cells to induce their migration to sites of inflammation and the production of Th2 cytokines. IL-33 also promotes the expansion of regulatory T cells and alternately activated macrophages while attenuating Th17 cell expansion and activation. IL-33 contributes to infection clearance by enhancing neutrophil sensitization to TLR and Dectin-1 signaling, phagocytic activity, and migration to sites of infection. It is upregulated in a wide variety of cells under inflammatory conditions.

The Tribio® Ultra-sensitive Human IL-33 Fast ELISA is a solid phase ELISA designed to measure human IL-33 levels in cell culture supernatants, serum, and plasma. The main feature is that the kit uses our novel proprietary approaches to combine samples and detection into a one-step instead of the complicated traditional methods. It makes the assay simple, easy, accurate, and ultra-sensitive. The measurement can detect the concentration as low as 0.5pg/mL, and finished in 2 hours, not need 5-6 hours (Fig. 1). The detection arrangement is from 0.5 to 2048 pg/mL. The levels of human IL-33 samples are parallel to the standard curves obtained using the kit standards linearly. Therefore, the kit can be used to determine relative mass values for natural human IL-33 protein.
