General description

Interleukin-2 (IL-2) is a potent lymphoid cell growth factor that exerts its biological activity mainly on T cells. Human IL-2 is a 15-16 kDa protein that contains 159 amino acid residues. This preparation contains monomeric and dimeric forms of IL-2.


For most in vitro applications, IL-2 exerts its biological activity in the concentration range of 0.1 to 1.0 ng / mL. The cells that respond are (partial list): T cells, NK cells, LAK cells.

Storage and stability

Lyophilized IL-2, although stable at room temperature, is best stored at -20 ° C. After rapid centrifugation, reconstitute in 100 mM acetic acid to a concentration of 0.1-1 mg/ml. This solution can be diluted in other buffered solutions or stored. Reconstituted IL-2 should be stored in undiluted aliquots at -20 ° C for up to six months. Avoid repeated freeze/thaw cycles.
