Product Specific Information
Recombinant mouse IL-5 is a non-glycosylated, disulfide-linked homodimer, containing two 113 amino acid chains, with a total molecular weight of 26.2 kDa. Purity is typically greater than 95% and endotoxin level less than 1 EU/ug.
The expected biological activity (ED50) is determined by the dose-dependent induction of TF-1 cell proliferation and is typically less than 2 ng/mL. The specific activity of this protein is 5x10^5 units/mg.
Reconstitute using sterile water at 0.1 mg/mL and centrifuge prior to opening vial. Gently pipet solution down the sides of the vial. DO NOT VORTEX sample. Store reconstituted material at -20°C and add 0.1% BSA for additional stability.

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.
