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.  Recombinant Rat IL-9 is a 14.3 kDa protein of 127 amino acid residues, including 10 cysteine residues that are fully conserved between the human and murine proteins.
