| Description : |
Interleukin 15 (IL-15) is a pleiotropic pro-inflammatory cytokine that promotes activation of T cells, neutrophils and macrophages, and is critical to dendritic cell function in several model systems. IL-15 has been shown to play a role in several inflammatory disorders, including rheumatoid arthritis, psoriasis and pulmonary inflammatory diseases. Emerging data suggest that IL-15 may serve as a good therapeutic target as there appears to be a beneficial effect of IL-15 neutralization in models of psoriasis and diabetes. |
| Form : |
Recombinant IL-15 was lyophilized from a concentrated (1mg/ml) solution with 5mM Tris pH 8.0. |
| Purity : |
Purity Greater than 98% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE. |
| Bio-activity : |
Recombinant IL-15 is fully biologically active when compared to standards. The ED50, as determined by the dose-dependant stimulation of the proliferation of mouse CTLL-2 cells, was found to be < 0.5 ng/ml. |
| Physical Appearance : |
Sterile Filtered white lyophilized (freeze-dried) powder. |
| Solubility : |
It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions. |
| Purity Greater than 98% as determined by : |
Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE. |
| Protein Content determined by : |
UV spectroscopy at 280 nm. Analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard. |
| Endotoxin Level : |
Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug. |

| Storage : |
Lyophilized product is very stable at -20 °C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended that a carrier protein (0.1% HSA or BSA) is added to the sample for long term storage. |
| Pathways : |
Cytokine-cytokine receptor interaction; Jak-STAT signaling pathway |
