IL-9 Antibody (PA5-47584) in Flow
Flow cytometry of IL-9 in Rat splenocytes were treated for 24 hours with 50 ng/mL PMA and 500 ng/mL Ca2+ ionomycin. Samples were incubated in IL-9 polyclonal antibody (Product # PA5-47584) or control antibody followed by NorthernLights™ 637-conjugated Anti-Sheep IgG Secondary Antibody. To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Target Information
Interleukin 9 (IL-9) is produced by activated T helper 2 (Th2) lymphocytes. IL-9 regulates many cell types involved in classical Th2-associated asthma responses, including B and T lymphocytes, mast cells, eosinophils, and epithelial cells. The mouse IL-9 cDNA encodes a 144 amino acid precursor protein with an 18 amino acid signal peptide that is cleaved to form the mature cysteine-rich protein with a molecular mass of 14 kDa. Native mouse IL-9 is heavily glycosylated. Recently, TGF beta has been reported to play an important role in the differentiation of IL-17-producing T helper cells and inducible regulatory T cells by reprogramming Th2 cells to secrete IL-9, thereby driving the differentiation of Th9 cells directly.
