特徴

• Interleukin-2 is a potent immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. IL-2/IL-2R signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine activated killer cells, monocytes, macrophages and oligodendrocytes. Human IL-2 is a 15.5kD protein containing 134 amino acid residues including one intrachain disulfide bond.
• Biological Activity:The ED50 as determined by the dose dependent stimulation of murine CTLL-2 cells is ≤0.1ng/ml, corresponding to a specific activity of ≥ 1x10e7u/mg.
