| IL-15 is an immunomodulating cytokine that stimulates the proliferation of T lymphocytes and shares many biological properties with IL-2. IL-15 exerts its biological activites primarily on T cells. It is also essential in the development, survival and activation of NK cells. Increased expression of IL-15 has been implicated with rheumatoid arthritis, inflammatory bowl disease and diseases affiliated with retroviruses HIV and HTLV-I. 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 13.2 kDa protein consisting of the following 114 amino acid residues. | | | Catalog # | I8437-01F | | Source | Escherichia coli. | | Biological Activity | Measured in a cell proliferation assay using CTLL-2 cells, the specific activity shall be not less than 2 x 10e6 units/mg. | | Endotoxin | 1EU/ug (LAL) | | Storage and Stability | Lyophilized powder may be stored at -20°C.
