- BACKGROUND
Description | 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 bowel disease and diseases affiliated with retroviruses HIV and HTLV-I. Human IL-15 is biologically active on M cells as measured by the dose-dependent stimulation of the proliferation of M CTLL cells. Recombinant human IL-15 is a 12.9 kDa protein consisting of 114 amino acid residues. |
---|---|
BiologicalActivity | The ED50 as determined by the dose-dependent stimulation of the proliferation of CTLL-2 cells was found to be ≤ 0.5 ng/ml, corresponding to a specific activity of ≥ 2 x 106 units/mg. |
Authenticity | Verified by N-terminal and Mass Spectrometry analyses (when applicable). |
Endotoxin | Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg). |
Protein Content | Verified by UV Spectroscopy and/or SDS-PAGE gel. |
Storage | -20°C |
Precautions | Animal-Free Recombinant Human IL-15 is for research use only and not for use in diagnostic or therapeutic procedures. |
