| Description |
The Recombinant Human Interleukin-15/IL15 was generated by the expression of a DNA sequence corresponding to 49-162aa of human IL15 in E.coli. The full-length of mature protein reached up to 97% in purity measured by SDS-PAGE and HPLC analyses. It was also verified to be fully biologically active through its effect on a cell proliferation assay using murine CTLL-2 cells (ED50<0.5 ng/ml, specific activity >2.0x106 IU/mg). The endotoxin of this IL10 is less than 1.0 EU/μg as determined by the LAL method. Proteins in-stock are offered now. The IL15 proteins are tag-free, but CUSABIO offers custom service for you to meet the need of specific tag(s). This recombinant IL15 protein may be used to produce anti-IL15 antibodies or in the immunology studies. IL15 is a pro-inflammatory cytokine that plays a central role in the development, survival, and activation of NK, T-, and B-cells. IL-15 binding to the IL-2/IL-15Rβ/γc heterodimeric receptor induces the activation of JAK-STAT, PI3K-Akt, and MAPK signaling pathway. The former pathway stimulates transcriptional activation such as bcl-2 and proto-oncogenes c-myc, c-fos, and c-jun, and the latter two pathways promote cell survival and activation. The anti-tumor effect of IL15 on the immune system has been reported, but IL15 also initiates and promotes several malignancies. |

| Form | Lyophilized powder |
| Buffer | Lyophilized from a 0.2 µm filtered PBS, pH 7.4 |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference. |

| Storage Condition | Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles. |
| Shelf Life | The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. |
| Lead Time | 5-10 business days |
| Notes | Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. |

| Function |
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. In neutrophils, stimulates phagocytosis probably by signaling through the IL15 receptor, composed of the subunits IL15RA, IL2RB and IL2RG, which results in kinase SYK activation.

| Subcellular Location | [Isoform IL15-S48AA]: Secreted.; [Isoform IL15-S21AA]: Cytoplasm. Nucleus. Note=IL15-S21AA is not secreted, but rather is stored intracellularly, appearing in the nucleus and cytoplasmic components. |
| Protein Families | IL-15/IL-21 family |
| Tissue Specificity | Most abundant in placenta and skeletal muscle. It is also detected in the heart, lung, liver and kidney. IL15-S21AA is preferentially expressed in tissues such as testis and thymus. |
