Recombinant Human IL-2 HQ

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. IL-2 may be of use as an anti-tumor agent in cancer therapy. Human and mouse IL-2 share 56% aa sequence identity and exhibit cross-species activity. The Recombinant Human IL-2 HQ contains 133 amino acids and a 16 a.a. histidine based tag for a total lenght of 149 a.a.

Lyophilized from a 0.2 um sterile filtered solution of PBS, pH 7.2.

Centrifuge vial prior to opening. It is recommended to reconstitute the lyophilized protein in sterile water to a concentration of no less than 100 ug/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). The optimal concentration should be determined by the user for each specific application.
