Applications

Recommended Concentration

Sample

Mouse IL-4 Sandwich Immunoassay

Recommended Concentration

Reagent

ELISA Capture (Matched Antibody Pair)

2-8 µg/mL

Use in combination with:

Detection Reagent: Mouse IL‑4 Biotinylated Antibody (Catalog # BAF404)

Standard: Recombinant Mouse IL-4 Protein (Catalog # 404-ML)

Neutralization

Measured by its ability to neutralize IL‑4-induced proliferation in the HT‑2 mouse T cell line. The Neutralization Dose (ND₅₀) is typically 0.1-0.6 µg/mL in the presence of 7.5 ng/mL Recombinant Mouse IL‑4.

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.

Scientific Data

Neutralization

Cell Proliferation Induced by IL-4 and Neutralization by Mouse IL-4 Antibody. Recombinant Mouse IL-4 (Catalog # 404-ML) stimulates proliferation in the HT-2 mouse T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL-4 (7.5 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse IL-4 Monoclonal Antibody (Catalog # MAB404R). The ND₅₀ is typically 0.1-0.6 µg/mL.

Background: IL-4

Interleukin-4 (IL-4), also known as B cell-stimulatory factor-1, is a monomeric, approximately 13-18 kDa Th2 cytokine that shows pleiotropic effects during immune responses (1‑4). It is a glycosylated polypeptide that contains three intrachain disulfide bridges and adopts a bundled four alpha -helix structure (5). Mouse IL-4 is synthesized with a 24 amino acid (aa) signal sequence. Mature mouse IL-4 shares 39%, 39%, and 59% aa sequence identity with bovine, human, and rat IL-4, respectively. Human, mouse, and rat IL-4 are species-specific in their activities (6-8). IL-4 exerts its effects through two receptor complexes (9, 10). The type I receptor, which is expressed on hematopoietic cells, is a heterodimer of the ligand binding IL-4 R alpha and the common gamma chain (a shared subunit of the receptors for IL-2, -7, -9, -15, and -21). The type II receptor on nonhematopoietic cells consists of IL-4 R alpha and IL-13 R alpha 1. The type II receptor also transduces IL-13 mediated signals. IL-4 is primarily expressed by Th2-biased CD4⁺ T cells, mast cells, basophils, and eosinophils (1, 2). It promotes cell proliferation, survival, and immunoglobulin class switch to IgG1 and IgE in mouse B cells, acquisition of the Th2 phenotype by naïve CD4⁺ T cells, priming and chemotaxis of mast cells, eosinophils, and basophils, and the proliferation and activation of epithelial cells (11‑14). IL-4 plays a dominant role in the development of allergic inflammation and asthma (13, 15).
