| 反应种属 | Mouse |
| 应用 | Western Blot,Immunocytochemistry,Neutralization |
| 目标/特异性 | Detects mouse IL‑5 in direct ELISAs and Western blots. Neutralizes the biological activity of recombinant mouse IL-5, but will not neutralize the biological activity of recombinant human IL-5. In direct ELISAs and Western blots, less than 5% cross‑reactivity with recombinant human IL-5 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Immunocytochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize IL‑5-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND50) is typically 0.4-0.9 µg/mL in the presence of 1.25 ng/mL Recombinant Mouse IL‑5. |

| 背景 | Interleukin 5 is a T cell-derived factor that promotes the proliferation, differentiation and activation of eosinophils. In mice, IL-5 has also been shown to be a growth and differentiation factor for B cells. Various names previously used to describe IL-5 include: T cell replacing factor (TRF), B cell growth factor II (BCGFII), B cell differentiation factor μ (BCDF μ), eosinophil differentiation factor (EDF) and eosinophil colony-stimulating factor (Eo-CSF). Biologically active IL-5 is a disulfide-linked homodimer. The cDNAs for murine and human IL-5 encode precursor proteins with signal peptides that are cleaved to form mature proteins containing 113 and 115 amino acid residues, respectively. Murine and human IL-5 are 70% identical in their amino acid sequences and show species cross-reactivity. The genes for human and mouse IL-5 have been mapped to chromosome 5 and chromosome 11, respectively; closely linked to the genes for IL-3, IL-4 and GM-CSF. IL-5 exerts its activity on target cells by binding to specific cell surface receptors. The functional high-affinity receptor for human IL-5 has been shown to be composed of a low-affinity IL-5 binding alpha -subunit and a non-binding common beta -subunit that is shared with the high-affinity receptors for GM-CSF and IL-3. |

Cell Proliferation Induced by IL‑5 and Neutralization by Mouse IL‑5 Antibody. Recombinant Mouse IL‑5 (Catalog # 405-ML) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑5 (1.25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-405-NA). The ND50 is typically 0.4-0.9 µg/mL. |
