Interleukin-15 (IL-15) is a potent lymphoid cell growth factor that exerts its biological activities primarily on T-cells. Human IL-15 is a 12.9 kDa protein containing 114 amino acid residues.

Product Source: Human

10 μg

For most in vitro applications, IL-15 exerts its biological activity in the concentration range of 0.1 to 10 ng/mL. Responding cells are (partial list): T-cells, NK cells, LAK cells.

Protein lyophilized from 10 mM Sodium Phosphate, pH 8.5.

The lyophilized powder, though stable at room temperature, is best stored at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. This solution can be diluted into other aqueous buffers and stored at 4°C for 1 week or -20°C for future use. Reconstituted IL-15 should be stored in working aliquots at -20°C. Avoid repeated freeze/thaw cycles.

Specific Activity: Human IL-15 is fully biologically active when compared to standards.The ED(50) as determined by the dose-dependent proliferation of CTLL-2 cells was found to be ≤ 0.5 ng/mL
