IL-33, also known as NFHEV and DVS 27, is a 30 kD proinflammatory protein that belongs to IL-1 superfamily. IL-33 is constitutively expressed in smooth muscle and airway epithelia. It is upregulated in arterial smooth muscle, dermal fibroblasts, and keratinocytes following IL-1α or IL-1β stimulation. IL-33 interacts with IL1RL1/ST2 receptor and IL-1 receptor accessory protein (IL1RAP) in order to activate intracellular molecules in the NF-κB and MAP kinase signaling pathways that drive production of type 2 cytokines (e.g. IL-5 and IL-13) from polarized Th2 cells. Recombinant IL-33 has been shown to enhance Th2-associated immune responses and potently increase mast cell proliferation and cytokine production.Product Details

ELISA Capture - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For use as an ELISA capture antibody, a concentration range of 0.25-1 µg/ml is recommended. It is recommended that the reagent be titrated for optimal performance. To obtain a linear standard curve, serial dilutions of IL-33 recombinant protein ranging from 1000-15.6 pg/ml are recommended.
- Application Notes
ELISA Capture: The purified Poly5163 antibody is useful as a capture antibody in a sandwich ELISA assay, when used in conjunction with the biotinylated Poly5163 antibody (Cat. No. 516303) as the detecting antibody and recombinant human IL-33 (Cat. No. 581809) as the standard.
AB_2561331 (BioLegend Cat. No. 516301)
- 270 aa with predicted molecular weight of 30 kD.
- Full length IL-33 localizes to the nucleus in HUVECs and transfectants C-terminal fragment, corresponding mature IL-33 is secreted.
- Cytokine that binds to and signals through IL1RL1/ST2 and its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Induces T helper type 2-associated cytokines.
- Binding to IL1RL1/ST2 and IL-1 receptor accessory protein.
- In sandwich ELISA, no cross-reactivity with mouse or rat IL-33.
