| Source | Human IL-15, amino acid Asn49-Ser162 (Accession # P40933), was expressed in E.coli. |
|---|---|
| Molecular Mass | The 114 amino acid recombinant protein has a predicted molecular mass of approximately 12.8 kD. The DTT-reduced and non-reduced protein migrates at approximately 11 kD and 7 kD by SDS-PAGE, respectively. The predicted N-terminal amino acid is Asn. |
| N-terminalSequence Analysis | Asn-Trp-Val-Asn-Val-Ile-Ser-Asp-Leu-Lys |
| Purity | >95%, as determined by Coomassie stained SDS-PAGE |
| Formulation | 0.1 µm filtered protein solution is in PBS. |
| Endotoxin Level | Less than or equal to 0.1 EU per μg protein as determined by the LAL method |
| Residual Host Cell Protein Content | ≤ 0.500 ng/μg by ELISA |
| Concentration | 500 µg/mL |
| Storage & Handling | Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |

| Activity | Cell-Vive™ GMP Recombinant Human IL-15 induces the proliferation of MO7e megakaryocytic leukemic cells in a dose-dependent manner. The ED50 for this effect is 2 - 10 ng/mL. The specific activity of Cell-Vive™ GMP Recombinant Human IL-15 (carrier-free) is ≥ 1.4 x 108 IU/mg when compared against an internal control. The internal control was calibrated against the WHO International Standard for Human IL-15 (NIBSC code: 95/554). |

| Structure | 13 kD non-glycosylated polypeptide |
|---|
| Distribution | IL-15 is expressed by DC, epithelial cells, human stromal cell line (IMTLH), fibroblasts, and monocytes. |
|---|
| Function | IL-15 stimulates the proliferation of activated T cells, NK cells and B cells. IL-15 induces immunoglobulin synthesis by B cells stimulated by anti-IgM or CD40 ligand. In addition, IL-15 promotes the development of dendritic cells, activates human neutrophils, and induces the production of proinflammatory cytokines from macrophages. |
