Additional Names:
p40 cytokine, T-cell growth factor p40
Background:
IL-9 is an immunoregulatory cytokine produced by IL-2 activated Th2 lymphocytes. IL-9 enhances the proliferation of T lymphocytes, mast cells, erythroid precursor cells and megakaryoblastic leukemia cell lines. Over-expression of IL-9 has been implicated in the pathogenesis of anaplastic lymphoma and Hodgkin?s disease. Whereas murine IL-9 can function on human cells, human IL-9 is inactive on mouse cells. Recombinant Human IL-9 is a 14.0 kDa protein of 127 amino acid residues, including 10 cysteine residues that are fully conserved between the human and murine proteins.
Biological Activity:
Determined by its ability to stimulate the proliferation of human MO7e cells. The expected ED50 is < 0.2 ng/ml, corresponding to a specific activity of > 5 x 106 units/mg.
