Applications
  •  
    Recommended
    Concentration
    Sample
  • Neutralization
    Measured by its ability to neutralize IL‑9-induced proliferation in the TS1 mouse helper T cell line. Moreau, F. J. et al. (1988) Nature 336:690. The Neutralization Dose (ND50) is typically 0.5-2.0 ng/mL in the presence of 0.05 ng/mL Recombinant Mouse IL‑9.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Cell Proliferation Induced by IL‑9 and Neutralization by Mouse IL‑9 Antibody. Recombinant Mouse IL‑9 (Catalog # 409-ML) stimulates proliferation in the TS1 mouse helper T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑9 (0.05 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse IL‑9 Monoclonal Antibody (Catalog # MAB4091). The ND50 is typically 0.5-2.0 ng/mL.

Background: IL-9

Mouse IL-9 was originally identified as a T cell-derived T cell growth factor III/P40 which could support the long term growth of certain mouse T helper clones in the absence of antigen or antigen-presenting cells. IL-9 can also prolong the in vitro survival of other T cell clones as well as potentiate the IL-2 dependent proliferation of mouse fetal thymocytes. However, this cytokine has no growth-stimulating activity on mouse cytolytic T cell clones or fresh T cells. Mouse IL-9 also has mast cell enhancing activity (MEA) and can enhance the mIL-3- or mIL-4-dependent proliferation of mouse bone marrow-derived mast cells. Furthermore, IL-9 will synergize with erythropoietin to support erythroid colony formation in vitro. The mouse IL-9 cDNA encodes a 144 amino acid residue precursor protein with an 18 amino acid signal peptide that is cleaved to form the mature cysteine-rich protein with a predicted molecular mass of 14 kDa. Mouse IL-9 contains four potential N-linked glycosylation sites and the native mIL-9 is a highly glycosylated protein. Human and mouse IL-9 share 56% amino acid sequence homology. Although mouse IL-9 is active on human cells, human IL-9 is not active on mouse cells.
