It is made in an animal-free, xeno-free format and supplied lyophilized from a 0.2 µm-filtered PBS solution without carrier protein, with purity \u0026gt;95% by SDS-PAGE and endotoxin \u0026lt;0.5 EU\/µg.\u003c\/p\u003e\n\u003cp\u003eIL-23 is used in immunology research on the regulation of immune responses, particularly T-cell differentiation and activation, in research on autoimmune diseases such as psoriasis and inflammatory bowel disease, and in studies of its influence on tumor growth and metastasis. It is also used in drug-discovery research on autoimmune disease. The manufacturer expresses this human protein in human cells, with extremely low endotoxin and high purity.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"bhp-qc-badge\"\u003eExpression system: Human cells · Tag-free · Animal-free\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eScientific Background\u003c\/h2\u003e\n\u003cp\u003eIL-23 is a heterodimeric cytokine made of a unique p19 subunit and a p40 subunit that it shares with IL-12. It is secreted by activated dendritic cells and macrophages.\u003c\/p\u003e\n\u003cp\u003eIL-23 binds a heterodimeric receptor complex of IL12RB1 and IL23R and activates the JAK-STAT signaling cascade. It acts mainly on memory T cells rather than naive T cells and increases production of proinflammatory cytokines such as IFNγ and IL-17. Through these effects IL-23 drives autoimmune inflammation, may contribute to autoimmune inflammatory diseases and may be important in tumorigenesis.\u003c\/p\u003e\n\u003ch2\u003eResearch Applications\u003c\/h2\u003e\n\u003cp\u003eIL-23 is used mainly in immunology and autoimmune-disease research; the main research areas are listed below.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eImmunology research: regulation of immune responses, particularly T-cell differentiation and activation.\u003c\/li\u003e\n\u003cli\u003eAutoimmune disease research: the role of IL-23 in psoriasis and inflammatory bowel disease.\u003c\/li\u003e\n\u003cli\u003eCancer research: influence of IL-23 on tumor growth and metastasis.\u003c\/li\u003e\n\u003cli\u003eDrug discovery: IL-23 as a target in autoimmune disease research.\u003c\/li\u003e\n\u003cli\u003eBasic research: mechanisms of immune response, inflammation and autoimmunity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProtein Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget\u003c\/th\u003e\n\u003ctd\u003eIL-23\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecies\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExpression system\u003c\/th\u003e\n\u003ctd\u003eHuman cells\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStructure\u003c\/th\u003e\n\u003ctd\u003eGlycosylated heterodimer (p19 and p40 subunits)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtein family\u003c\/th\u003e\n\u003ctd\u003eHeterodimeric interleukin (p40 subunit shared with IL-12)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTag\u003c\/th\u003e\n\u003ctd\u003eTag-free\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAnimal origin\u003c\/th\u003e\n\u003ctd\u003eAnimal-free \/ xeno-free\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular weight\u003c\/th\u003e\n\u003ctd\u003e55 kDa.
