May promote the transition between innate and adaptive immunity. Induces the production of IgG1 and IgG3 in B-cells (By similarity). Implicated in the generation and maintenance of T follicμlar helper (Tfh) cells and the formation of germinal-centers. Together with IL6, control the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection (By similarity). May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regμlate proliferation of mature B- and T-cells in response to activating stimμli. In synergy with IL15 and IL18 stimμlates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation (By similarity).\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Interleukin-21, IL-21, Za11, IL21\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodified\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Recombinant protein of human IL21.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB 1:1000~1:2000\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: IL21 polyclonal antibody detects endogenous levels of IL21 protein.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 19 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
