特徴

• IL-6 is a pleiotropic cytokine that plays an important role in host defense by regulating immune and inflammatory responses. Produced by T cells, monocytes, fibroblasts, endothelial cells and keratinocytes, IL-6 has diverse biological functions. It stimulates B-cell differentiation and antibody production, synergizes with IL-3 in megakaryocyte development and platelet production, induces expression of hepatic acute-phase proteins, and regulates bone metabolism. IL-6 signals through the IL-6 receptor system that consists of two chains, IL-6Ra and gp130. Murine IL-6 is inactive on human cells, while both human and murine are equally active on murine cells. Recombinant human IL-6 is a 20.9kD protein containing 184aa residues.
• Biological Activity:Fully biologically active when compared to standards. The ED50 was determined by the dose dependent stimulation of the proliferation of IL-6 dependent murine 7TD1 cells is ≤0.1ng/ml, corresponding to a specific activity of ≥1x10e7units/mg.
