| Short Description: |
Recombinant-Human IL-21-No-tag protein was developed from hek293 cells and has a target region of No-tag. For use in research applications. |
| Formulation: |
Lyophilized from a 0.22 Mu m filtered solution of PBS, pH 7.4. |
| Storage Instruction: |
Store at-20°C for up to 1 year from the date of receipt, and avoid repeat freeze-thaw cycles. |
| Immunoreactivity: |
Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is 2.7-10.8 ng/mL, corresponding to a specific activity of 9.3×104~3.7×105 units/mg. |

| Immunogen: |
Recombinant Human IL-21 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln32-Ser162) of human IL-21 (Accession #NP_068575.1) fused with no additional amino acid. |
| 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. Implicated in the generation and maintenance of T follicular helper (Tfh) cells and the formation of germinal-centers. Together with IL6, control the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection. 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. |
