INTERLEUKIN 15 HUMAN

General description

Interleukin-15 (IL-15) is an immunomodulating cytokine. The gene encoding it is localized on chromosome 4q31. Human IL-15 is biologically active on mouse cells as measured by the dose-dependent stimulation of the proliferation of mouse CTLL cells. Recombinant human IL-15 is a 12.9kDa protein consisting of 115 amino acid residues.

Biochem/physiol Actions

Interleukin-15 (IL-15) stimulates the proliferation of T lymphocytes and shares many biological properties with IL-2. It exerts its biological activities primarily on T cells. It is also essential in the development, survival and activation of NK cells. On binding to its receptor, IL-15 is indirectly involved in activating proto-oncogenes. Increased expression of IL-15 has been implicated with rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis and diseases affiliated with retroviruses like human immunodeficiency virus (HIV) and human T-lymphotropic virus-1 (HTLV-I).

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
