背景说明: IL-21 induces the production of IgG1 and IgG3 in B-cells. 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.

英文别名: Interleukin-21,IL-21, Za11, IL21

描述:

Recombinant Human Interleukin-21 is produced by our E.coli expression system and the target gene encoding Gln23-Ser155 is expressed.

Accession: Q9HBE4

中文别名: Interleukin-21蛋白; IL-21蛋白

来源: Escherichia coli.

纯度: Greater than 95% as determined by reducing SDS-PAGE.

内毒素水平: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.

形态: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH7.4.

溶解方法: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

储存/保存方法: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
