IL-21 may promote the transition between innate and adaptive immunity. IL-21 may have a role in proliferation and maturation of natural killer cells in synergy with IL15. IL-21 stimulates interferon gamma production in T-cells and natural killer cells by synergy with IL15 and IL18. Dysregulation of IL-21 has a role in multiple immune-mediated diseases including lupus, psoriasis and chronic inflammatory diseases.\u003c\/p\u003e \n\n\u003cp\u003eAlternate Names: Interleukin-21; IL-21; Za11; IL21\u003c\/p\u003e\n\n\u003cp\u003eDescription: Recombinant Human Interleukin-21 is produced by our E.coli expression system and the target gene encoding Gln30-Ser162 is expressed.\u003c\/p\u003e\n\n\u003cp\u003eAccession: Q9HBE4\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 15.6 KDa\u003c\/p\u003e\n\n\u003cp\u003eApparent Molecular Weight: 16 KDa, reducing conditions\u003c\/p\u003e\n\n\u003cp\u003eStorage Condition: Lyophilized protein should be stored at \u0026lt; -20°C, though stable at room temperature for 3 weeks.
