General description

Interleukin-11 (IL-11) is a potent lymphoid cell growth factor which stimulates the growth and survivability of certain B-cells and T-cells. Human IL-11 is a 19.1 kDa protein containing 179 amino acid residues.


For most in vitro applications, IL-11 exerts its biological activity in the concentration range of 0.1 to 10.0 ng/mL. Responding cells are (partial list): Certain B-cells and T-cells.

Storage and Stability

The lyophilized powder, though stable for a few weeks at room temperature, is best stored at -20°C. After a quick spin, reconstitute in water to a concentration of 0.5-1.0 mg/mL. Please note: This solution is slow to dissolve. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or -20°C for future use. Reconstituted IL-11 should be stored in undiluted aliquots at -20°C for up to six months.

Biochem/physiol Actions

The ED(50) as determined by the dose-dependent stimulation of the proliferation of mouse T11 cells is ≤ 2 ng/mL
