Description :
Interleukin-15 (IL-15) is a potent lymphoid cell growth factor which exerts its biological activities primarily on T cells. Human IL-15 is a 13 kDa protein containing 114 amino acid residues.

Source:
E.coli

Formulation:
The sterile filtered solution was lyophilized with no additives.

Stability:
The lyophilized protein is stable for a few weeks at room temperature, but best stored at -200C. Reconstituted human IL-15 should be stored in working aliquots at -200C.

Purity:
Greater than 98% by SDS-PAGE analyses. Endotoxin level is less than 0.1 ng per �g (1EU/�g).

Reconstitution:
We recommend a quick spin followed by reconstitution in water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at 40C for 1 week or stored at -200C for future use.

Biological Activity:
The ED50 as determined by the dose-dependent stimulation of the proliferation of CTLL-2 cells was found to be < 0.5 ng/ml, corresponding to a specific activity of > 2 x 106 units/mg.
