Description

IL-33 belongs to the IL-1 family and is closely related in structure to IL-18 and IL-1β. IL-33, IL-1β, and IL-18 are synthesized as biologically inactive precursors and are cleaved by the enzyme caspase-1 to be secreted as active mature forms. IL-33 stimulates target cells by binding to the IL-1R/TLR superfamily member ST2 and, subsequently, activates NF-κβ and MAPK pathways via identical signalling events to those observed for IL-1β. In addition, IL-33 is a nuclear factor (NF-HEV) abundantly expressed in high endothelial venules from lymphoid organs that associate with chromatin and exhibit transcriptional regulatory properties.

Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Activity
ED50 = 0.1 - 0.5 ng/mL as determined by the dose-dependent stimulation of D10.G4.1 cell proliferation. Deep Blue Cell Viability™ Kit (Cat. No. 424701) is used to measure the proliferation.

Application Notes

BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue-ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are validated in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at tech@biolegend.com.

Antigen Details

Structure
Cytokine
Distribution

IL-33 mRNA is expressed in a broad range of human tissues, such as heart, small intestine, brain, ovary, testis, pancreas, and colon. Higher IL-33 expression was detected in human keratinocyte, fibroblast, myocyte, and alveolar cells

Function
IL-33 drives production of Th2-associated cytokines from in vitro polarized Th2 cells. In mice, IL-33 injection induced the expression of IL-4, IL-5, and IL-13 and led to severe pathological changes in the lung and the digestive tract. In addition, IL-33 acts as a chemoattractant for Th2 cells, both in vitro and in vivo. TNF-α and IL-1β are activators of IL-33 transcription in fibroblasts and keratinocytes.
Interaction
Th2 cells, mast cells, basophils, eosinophils and natural killer cells
Ligand/Receptor
IL-1 family receptor T1/ST2 and IL-1RAcP (IL-1 receptor associated protein).
Bioactivity
Measured by its ability to induce proliferation of D10.G4.1 cells.
Biology Area
Cell Biology, Immunology, Stem Cells, Transcription Factors
Molecular Family
