Recombinant Human IL-21 Protein

  • 表达系统: E. coli
  • Accession #: Q9HBE4
  • 蛋白标签: No tag
  • 生物活性: 1. Measured by its ability to enhance IFN-gamma secretion in NK-92 human natural killer lymphoma cells. The ED50 for this effect is ≤ 2.0 ng/mL. 2. Recombinant Human IL-21 stimulates cell proliferation of the CTLL-2 mouse cytotoxic T cell line. The ED50 for this effect is typically less than 40 ng/mL.
  • 内毒素水平: <0.01 EU/μg

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.

生物活性 1. Measured by its ability to enhance IFN-gamma secretion in NK-92 human natural killer lymphoma cells. The ED50 for this effect is ≤ 2.0 ng/mL. 2. Recombinant Human IL-21 stimulates cell proliferation of the CTLL-2 mouse cytotoxic T cell line. The ED50 for this effect is typically less than 40 ng/mL.
