Recombinant Human IL-15細胞因子
| Known as | Interleukin-15; IL-15; IL15 |
|---|---|
| Derived from | E.coli |
| Purity | Measured by the dose dependent stimulation of mouse CTLL-2 cell proliferation.ED50 is less than 0.5 ng/ml. Specific Activity of 2.0 x 10^6 IU/mg.Greater than 95% as determined by reducing SDS-PAGE. |
| Formulation | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.0. |
| Shipping | The product is shipped at ambient temperature.Upon receipt, store it immediay at the temperature listed below. |
| Storage | 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 9 months |
| Reconstitution | Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100μg/ml.Dissolve the lyophilized protein in 7X PBS.Please aliquot the reconstituted solution to minimize freeze-t cycles. |
| Endotoxin | Less than 0.1 ng/ug (1 IEU/ug). |

| Background | Human Interleukin 15 (IL-15) is a cytokine that regulates T cell and natural killer cell activation and proliferation. IL-15 binds to the alpha subunit of the IL15 receptor (IL-15RA) with high affinity. IL-15 also binds to the beta and gamma chains of the IL-2 receptor, but not the alpha subunit of the IL2 receptor. IL-15 is structurally and functionally related to IL-2. Both cytokines share some subunits of receptors, allowing them to compete for and negatively regulate each other's activity. The number of CD8+ memory T cells is controlled by a balance between IL-15 and IL-2. Despite their many overlapping functional properties, IL-2 and IL-15 are, in fact, quite distinct players in the immune system. IL-15 is constitutively expressed by a wide variety of cell types and tissues, including monocytes, macrophages and DCs. Mature Human IL-15 shares 70% amino acid sequence identity with Mouse and Rat IL-15. |
Recombinant Human Interleukin-15 is produced by our E.coli expression system and the target gene encoding Asn49-Ser162 is expressed.
