| 反应种属 | Mouse |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects mouse IL-9 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 5% cross-reactivity with human IL-9 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL 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 0.5-1.5 µg/mL in the presence of 0.05 ng/mL Recombinant Mouse IL‑9. |

| 背景 | 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. In addition to its activities on 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 gene for mIL-9 has been mapped to mouse chromosome 13. 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 IL-9 was independently cloned as a novel growth factor which is mitogenic for the human megakaryoblastic leukemic cell line, M07e. Human and mouse IL-9 share 56% and 67% homology at the amino acid and nucleotide levels, respectively. Although mouse IL-9 is active on human cells, human IL-9 is not active on mouse cells. |

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 Goat Anti-Mouse IL‑9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF409). The ND50 is typically 0.5-1.5 µg/mL. |
