| Description : |
Interleukin-15 (IL-15) is a cytokine with structural similarity to Interleukin-2 (IL-2). Like IL-2, IL-15 binds to and signals through a complex composed of IL-2/IL-15 receptor beta chain (CD122) and the common gamma chain (gamma-C, CD132). IL-15 is secreted by mononuclear phagocytes (and some other cells) following infection by virus(es). This cytokine induces cell proliferation of natural killer cells; cells of the innate immune system whose principal role is to kill virally infected cells. |

| Endotoxin : |
<0.1 EU per 1 μg of the protein by the LAL method. |
| Bio-activity : |
Measure by its ability to induce CTLL-2 cells proliferation. The ED50 for this effect is <10 ng/mL. The specific activity of recombinant mouse IL-15 is approximately >1x 10^5 IU/mg. |
| Purity : |
>98% as determined by SDS-PAGE. Ni-NTA chromatography |
| Storage Buffer : |
The protein was lyophilized from a solution containing 1X PBS, pH 7.4. |
| Reconstitution : |
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved. |
| Storage : |
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. |
| Notes : |
Please use within one month after protein reconstitution. |
