IL-9, human recombinant | 4152

Interleukin 9 (IL-9) is cytokine produced by a subgroup of helper T cells, known as Th2 cells. IL-9 signals through its receptor IL-9R to induce cell proliferation and survival. Genetically, IL-9 has been identified as a gene associated with asthma. Recombinant human IL-9 is a non-glycosylated protein, containing 127 amino acids and having a molecular mass of 14 kDa.
