Human Recombinant IL9 (from E. coli)
Proteins and Peptides

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 murine proteins. Manufactured using all Animal-Free reagents.
