- Extra Details:
- Interleukin-15 (IL-15) is an immunomodulating cytokine that stimulated the proliferation of T lymphocytes. It shares many biological properties with IL-2. IL-5 is a potent lymphoid cell growth factor that exerts its biological activities primarily on T cells. It is essential in the development, survival and activation of NK cells. Increased expression of IL-15 has been implicated with rheumatoid arthritis, imflammatory bowl disease and diseases affiliated with retroviruses HIV and HTLV-I. Human IL-15 is a 12.9 kD protein containing 114 amino acid residues. Biological Activity: Fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of the proliferation of CTLL-2 cells was found to be ≤ 0.5ng/ml, corresponding to a specific activity of ≥2x10e6 units/mg.
