IL-23 p19 Rat anti-Mouse, eFluor® 660, Clone: fc23cpg, eBioscience
Rat Monoclonal Antibody
Manufacturer: Invitrogen 50702382
Description: This fc23cpg monoclonal antibody reacts with the p19 subunit of mouse IL-23, a heterodimeric cytokine made up of two disulfide-linked subunits, p40 and p19. It is closely related to IL-12, with which it shares the p40 subunit. IL-23 signals through a heterodimeric receptor expressed on activated T cells, macrophages, and dendritic cells. The receptor shares the IL-12Rbeta1 chain with IL-12, while the IL-23R chain is unique to the IL-23 receptor complex. Binding of IL-23 to its receptor activates Jak/STAT pathways similarly to IL-12, but the two cytokines exhibit distinct functions. Unlike IL-12, which induces T-bet and Th1 differentiation, IL-23 signaling results in RORgammat expression and supports CD4^+ T cells with the Th17 phenotype Dendritic cells and macrophages produce IL-23 in response to TLR2, TLR4, and TLR8 ligands, as well as agonists of the beta-glucan receptor, Dectin-1. Our studies suggest donor, kinetics and type of stimulant can result in variation in IL-23 expression levels. Recent publications suggest the p19 subunit may also exist in the absence of association with p40. Applications Reported: This fc23cpg antibody has been reported for use by intracellular staining and flow cytometric analysis. Applications Tested: This fc23cpg antibody has been tested by intracellular staining and flow cytometric analysis. This can be used at less than or equal to 0.06 µg per test.A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered. The p19 shares sequence similarity with IL-6 subfamily members and is distantly related to the p35 subunit of IL-12. It shows no biological activity by itself; instead, it combines with the p40 subunit of IL-12 to form a biologically active, composite cytokine, IL-23. IL-23 shares some in vivo functions with IL-12, including the activation of the transcription factor Stat4. Similar to IL-12, human IL-23 stimulates IFN-g production and proliferation of PHA blast T cells, as well as in CD45 RO (memory) T cells. Ubiquitous transgenic expression of the IL-23 subunit p19 induces multiorgan inflammation, runting, infertility and premature death.
