Description
Interleukin 15 (IL-15) is a 12.65 kDa cytokine with 114 amino acid residues and is primarily produced from mononuclear phagocytes like dendritic cells, monocytes, and macrophages. IL-15 plays a critical role in the innate immune system when IL-15 binds to the IL-15 receptor. In addition, IL-15 mediates biological functions, such as the proliferation of natural killer cells and T cells, preventing the immune cells from apoptosis by activating STAT3 /JAK and PI3K/ALT signaling pathways.
Storage & Handling
Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.

Form
Lyophilized
Formulation
The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 7.4. If you have any concerns or special requirements, please confirm with us.
Purity
>95% as determined by SDS-PAGE.
Molecular weight
The protein has a calculated MW of 14.06 kDa. The protein migrates as 11-17 kDa under reducing condition (SDS-PAGE analysis).
Activity
Measure by its ability to induce proliferation in TF-1 cells. The ED₅₀ for this effect is <5.5 ng/mL.
Endotoxin
<0.01 EU per 1 μg of the protein by the LAL method.

Reconstitution
Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
