Scientific Data Images for Human IL-4 Antibody (3007)

IL-4 antibody in Human PBMCs by Immunocytochemistry (ICC).

IL‑4 in Human PBMCs.

IL-4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with PHA using Mouse Anti-Human IL-4 Monoclonal Antibody (Catalog # MAB304) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (yellow; Catalog # NL007) and counterstained with DAPI (blue).

Cell Proliferation Induced by IL‑4 and Neutralization by Human IL‑4 Antibody.

Cell Proliferation Induced by IL‑4 and Neutralization by Human IL‑4 Antibody.

Recombinant Human IL-4 (Catalog # 204-IL) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-4 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-4 Monoclonal Antibody (Catalog # MAB304). The ND50 is typically 0.03-0.1 µg/mL.

Applications for Human IL-4 Antibody (3007)

Application
Recommended Usage

Immunocytochemistry

8-25 µg/mL
Sample: Immersion fixed human peripheral blood mononuclear cells stimulated with PHA

Western Blot

1 µg/mL
Sample: Recombinant Human IL‑4 (Catalog # 204-IL)

Neutralization

Measured by its ability to neutralize IL‑4-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 0.03-0.1 µg/mL in the presence of 0.5 ng/mL Recombinant Human IL‑4.

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 (1‑3). It is a glycosylated polypeptide that contains three intrachain disulfide bridges and adopts a bundled four alpha -helix structure (4). Human IL-4 is synthesized with a 24 aa signal sequence. Alternate splicing generates an isoform with a 16 aa internal deletion. Mature human IL-4 shares 55%, 39%, and 43% aa sequence identity with bovine, mouse, and rat IL-4, respectively. Human, mouse, and rat IL-4 are species-specific in their activities (5-7). IL-4 exerts its effects through two receptor complexes (8, 9). 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 non-hematopoietic 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 IgG4 and IgE in human 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 (10-13). IL-4 plays a dominant role in the development of allergic inflammation and asthma (12, 14).
