Human IL-5 Antibody Summary
Accession # P05113
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.
Cell Proliferation Induced by IL‑5 and Neutralization by Human IL‑5 Antibody. Recombinant Human IL‑5 (Catalog # 205-IL) stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL‑5 (1.25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-205-NA). The ND50 is typically 0.3-0.9 µg/mL.
Preparation and Storage

- 1 month, 2 to 8 °C under sterile conditions after reconstitution.
- 6 months, -20 to -70 °C under sterile conditions after reconstitution.
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.
