详细内容
Human Interleukin-15 (IL-15) is expressed by the IL15 gene located on the chromosome 4. It shares approximately 97% ａnd 73% sequence identity with simian ａnd murine IL-15, respectively. Both human ａnd simian IL-15 are active on murine cells. IL-15 is secreted by mononuclear phagocytes (and some other cells), especially macrophages following infection by virus. It possesses a variety of biological functions, including stimulating ａnd maintaining of cellular immune responses, especially regulating T ａnd natural killer (NK)
cell activation ａnd proliferation. In additionally, it shares many biological properties with IL-2, including T, B ａnd NK cell-stimulatory activities. IL-15 signals through a complex composed of IL-2/IL-15 receptor beta chain.

▍Purity
Purity >90% as determined by SDS-PAGE.
▍Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization. Contact us for customized product form or formulation.
▍Reconstitution
Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots ａnd stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.
▍Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to ⁻⁷0°C for 12 months in lyophilized state;
⁻⁷0°C for 3 months under sterile conditions after reconstitution.
▍SDS-PAGE
Human IL-15, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
