IL-33 belongs to the IL-1 family and is closely related in structure to IL-18 and IL-1b. IL-33 is synthesized as a biologically inactive precursor and is cleaved by the enzyme caspase-1 and secreted as a mature active form. IL-33 stimulates target cells by binding to the IL-1R/TLR superfamily member ST2 and subsequently activates NF-κB and MAPK pathways via identical signaling events to those observed for IL-1b. IL-33 is an inducer of Th2 cytokines such as IL-5 and IL-13. It is also a nuclear factor (NF-HEV) abundantly expressed in high endothelial venules from lymphoid organs that associates with chromatin and exhibits transcriptional regulatory properties.
BioLegend’s LEGEND MAX™ Human IL-33 ELISA kit is a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a capture antibody. This kit is specifically designed for the accurate quantitation of human IL-33 from cell culture supernatant, serum, plasma and other biological fluids. It is analytically validated with ready-to-use reagents.
