Human IL-5 Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL-5 in direct ELISAs. In direct ELISAs, approximately 3% cross-reactivity with recombinant mouse IL-5 is observed.
Source
Monoclonal Mouse IgG1 Clone # 14611
Purification
Protein A or G purified from ascites
Immunogen
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL‑5
Ile20-Ser134
Accession # P05113
Formulation
Lyophilized from a 0.2 μm filtered solution in Tris and NaCl with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.
Label
Unconjugated

Applications

Recommended Concentration
Sample
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 0.01-0.03 µg/mL in the presence of 0.5 ng/mL Recombinant Human IL‑5.

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) as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human IL-5 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-5 Monoclonal Antibody (Catalog # MAB205). The ND50 is typically 0.01-0.03 µg/mL.

Background: IL-5

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. 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.
