产品详细信息
Description: The antibody eBio473P19 reacts with the p19 subunit of human IL-23. The eBio473P19 antibody was generated from immunization with authentic, insect cell-expressed, recombinant human IL-23 heterodimer.
The use of a p19-specific capture antibody and a p40-specific detection antibody yields a human IL-23 sandwich ELISA exquisitely specific for human IL-23. IL-12 p40 monomer and IL-12 p70 were run in the assay at 200 ng/mL with no interference or cross-reactivity observed. A panel of 20 unrelated cytokines was also run in the IL-23 ELISA at 100 ng/mL with no cross reactivity observed. The assay has been validated by specific detection of significant levels of native human IL-23 protein in supernatants from a variety of different activated dendritic cell populations.
IL-23 is a heterodimeric cytokine composed of the p40 subunit of IL-12 disulfide-linked with a protein p19. p19, like p35 of IL-12, is biologically inactive by itself. IL-23 interacts with IL-12Rbeta1 and an additional, novel beta2-like receptor subunit with STAT4 binding domain, termed IL-23R. IL-23 is secreted by activated mouse and human dendritic cells. Biological activities of mouse IL-23 are distinct from those of mouse IL-12. Mouse IL-23 was found not to induce significant amounts of IFN-g. Mouse IL-23 does induce strong proliferation of memory T cells (but not naive T cells), whereas IL-12 has no effect on memory cells. Additionally, mouse IL-23 (but not IL-12) can activate mouse memory T cells to produce the proinflammatory cytokine IL-17. Human IL-23 has biological properties which are less distinct from human IL-12; human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN-g production by naive and memory T cells, as compared to IL-12. IL-23-dependent, IL-17-producing CD4+ T cells (Th-17 cells) have been identified as a unique subset of Th cells that develops along a pathway that is distinct from the Th1- and Th2- cell differentiation pathways. The hallmark effector molecules of Th1 and Th2 cells, e.g., IFN-g and IL-4, have each been found to negatively regulate the generation of these Th-17 cells. More recently, de novo differentiation of Th-17 cells in the absence of IL-23 has been demonstrated by treatment of naive CD4 cells with TGF beta1 and IL-6.
Applications Reported: This eBio473P19 antibody has been reported for use in immunoblotting (WB), and ELISA.
Applications Tested: The eBio473P19 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of human IL-23 (p19p40) protein levels in combination with the biotinylated (p40-specific) C8.6 antibody (13-7129) for detection and recombinant human IL-23 (14-8239) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 2.5-8.0 µg/mL. A standard curve consisting of doubling dilutions of the recombinant IL-23 standard over the range of 2000 pg/mL - 15 pg/mL should be included in each ELISA plate. TMB, rather than ABTS, should be used as the substrate.The antibody eBio473p19 also works in immunoblotting under both reducing and nonreducing conditions at 2 µg/mL.
*eBio473P19 is a cocktail of the two clones, eBio11P19 and eBio25P19 at 0.5 mg/mL each. Please contact Tech Support for more information regarding the concentration.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
