Background: Interleukin-9 (IL-9) is a secreted protein that belongs to the IL-7/IL-9 family.Mature mouse IL-9 shares 57% and 74% amino acid sequence identity with human and rat IL-9, respectively. IL-9 supports IL-2 independent and IL-4 independent growth of helper T-cells. IL-9 stimulates cell proliferation and prevents apoptosis. It functions through the IL-9 receptor (IL-9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. IL-9 has been identified as a candidate gene for asthma. IL-9 is a determining factor in the pathogenesis of bronchial hyperresponsiveness.
Activity: Measure by its ability to induce proliferation in MO7e cells. The ED50 for this effect is < 0.25 ng/mL. The specific activity of recombinant human IL-9 is approximately > 5 x106 IU/ mg.
