Cat.No. : Il21-153M
Product Overview : Purified recombinant protein of Mouse interleukin 21 (Il21) without tag was expressed in E.coli.
Description : Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG1 and IgG3 in B-cells. 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.
Source : E. coli
Species : Mouse
Bio-activity : Measured by its ability to increase proliferation in mouse splenocytes induced by anti-hCD40 mAb. The expected ED50 is 15-20 ng/ml.
Molecular Mass : 15 kDa
Endotoxin : Endotoxin level is < 0.1 ng/µg of protein (< 1 EU/µg)
