Interleukin-15 (IL-15) is a cytokine with structural similarity to Interleukin-2 (IL-2). Like IL-2, IL-15 binds to and signals through a complex composed of IL-2/IL-15 receptor beta chain (CD122) and the common gamma chain (gamma-C, CD132). IL-15 is secreted by mononuclear phagocytes (and some other cells) following infection by virus(es). This cytokine induces cell proliferation of natural killer cells; cells of the innate immune system whose principal role is to kill virally infected cells.

Measure by its ability to induce proliferation in TF-1 cells. The ED50 for this effect is <5.5 ng/mL.
Endotoxin level:<0.01 EU per 1 ug of the protein by the LAL method.
Calculated Molecular Weight:14.1 kDa
Formulation:The protein was lyophilized from a solution containing 1X PBS, pH7.4.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability and Storage:
Lyophilized protein should be stored at -20 degrees Celsius for 1 year. Upon reconstitution, store at 2 degrees Celsius to 8 degrees Celsius 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 degrees Celsius or -80 degrees Celsius for 3-6 months.
