| Purity |
> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
|
| Endotoxin Level | Less than 0.05EU per μg by the LAL method. | |
| Biological Activity | Measured in a cell proliferation assay using CTLL2 cells. The ED50 for this effect is 0.1 0.3 ng/mL. The specific activity of recombinant IL-15, Human is > 1 x 10^7 units/mg, which is calibrated against the IL-15, Human reference standard (NIBSC code: 95/554). Test result was comparable to standard batch. | |
| Expression System | E.coli | |
| Theoretical Molecular Weight | 12.8 kDa | |
| Apparent Molecular Weight | The protein has a predicted MW of 12.8 kDa same as Bis-Tris PAGE result. | |
| Formulation | Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NACI (pH 7.5). | |
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. | |
| Storage & Stability | Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background | Interleukin 15 (IL-15) is a widely expressed 14 kDa cytokine that is structurally and functionally related to IL-2 and plays an important role in many immunological diseases. IL-15 is a cytokine that stimulates the proliferation of T-lymphocytes. Stimulation by IL15 requires interaction of IL15 with components of the IL2 receptor, including IL2RB and probably IL2RG but not IL2RA. |
| Synonyms | L15; IL-15; IL-15MGC9721; Interleukin-15 |
