英文别名	CVID11; IL21; IL-21; IL-21Za11interleukin-21; interleukin 21; interleukin-21 isoform; Za11
规格或纯度	Animal Free, >97% (SDS-PAGE, HPLC), Active, E.coli, No tag, 30-162 aa
产品介绍	Purity >97%（SDS-PAGE,HPLC） Function Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells (By similarity). May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation.
