Biolegend, 435908, LEGEND MAX™ Human IL-33 ELISA Kit

IL-33 belongs to the IL-1 family and is closely related in structure to IL-18 and IL-1b. IL-33, IL-1β, and IL-18 are synthesized as biologically inactive precursor and are cleft 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-κB and MAPK pathways via identical signaling events to those observed for IL-1β. In addition, IL-33 as 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 polyclonal goat anti-human IL-33 capture antibody. The detection antibody is a biolinylated polyclonal goat anti-human IL-33 antibody. BioLegend's LEGEND MAX™ Human IL-33 ELISA Kit is specifically designed for the accurate quantitation of Human IL-33 from cell culture supernatant, serum, plasma or other bodily fluids. It is ready-to-use, accurate, and sensitive.
