Background

Interleukin 2 (IL-2) is a potent immunoregulatory growth factor produced by T-cells following stimulation by mitogens or allogens. IL-2 promotes growth and differentiation of various cells of the immune system, such as activated T-cells and B-cells, NK cells, lymphokine activated killer cells, monocytes and macrophages. It is essential for proper immune response, it may also be an important factor in the natural suppression of autoimmunity. IL2 may be of use as an anti-tumor agent in cancer therapy. Recombinant human IL2 is a 15.5 kDa protein, consisting of 134 amino acid residues. Human and mouse IL-2 share 56% aa sequence identity and exhibit cross-species activity.
