| 应用 | Western Blot(0.1 µg/mL) Immunocytochemistry(5-15 µg/mL) |
| 目标/特异性 | Detects rat IL‑5 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse IL‑5 is observed and 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 2-6 µg/mL in the presence of 1.25 ng/mL Recombinant Rat 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 formurine, human and rat IL-5 encode precursor proteins with signal peptides that are cleaved to form mature proteins containing 113, 115, and 113 amino acid residues, respectively. Rat IL-5 is 94% and 70% identical to mouse and human IL-5, respectively. The genes for human and mouse IL-5 have been mapped to chromosome 5 and chromosome 11, respectively; closely linked tothe 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 sharedwith the high-affinity receptors for GM-CSF and IL-3. |

Cell Proliferation Induced by IL‑5 and Neutralization by Rat IL‑5 Antibody. Recombinant Rat IL‑5 (Catalog # 545-RL) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat IL‑5 (1.25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Rat IL‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF545). The ND50 is typically 2‑6 µg/mL. |
