目标/特异性 | Detects human IL‑4 R alpha in direct ELISAs and Western blots. In direct ELISAs, no cross-reactivity with recombinant human (rh) IL-9 R, recombinant mouse IL-4 R, rhIL-5 R alpha, rhIL-5 R beta, rhIL-13 R alpha 1, or rhIL-13 R alpha 2 is observed. |
使用方法 | Western Blot: 1 µg/mL Flow Cytometry: 0.25 µg/106cells Immunohistochemistry: 8-25 µg/mL 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 3-6 ng/mL in the presence of 0.2 ng/mL Recombinant Human IL‑4. |

R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Cancer-initiating cells from colorectal cancer patients escape from T cell-mediated immunosurveillance in vitro through membrane-bound IL-4. | |

背景 | Interleukin 4 receptor (IL-4 R) is the transmembrane ligand binding subunit of the heterodimeric IL-4 receptor complex. In the type I receptor complex, IL-4 R associates with the common gamma chain, whereas in the type II receptor complex, it associates with IL-13 R alpha 1. IL-4 R is expressed by B cells, T cells, monocytes and macrophages. |

Detection of IL‑4 R alpha in Daudi Human Cell Line by Flow Cytometry. Daudi human Burkitts lymphoma cell line was stained with Mouse Anti-Human IL‑4 R alpha Monoclonal Antibody (Catalog # MAB230, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B). | |
IL‑4 R alpha in Human Lymph Node. IL‑4 R alpha was detected in immersion fixed paraffin-embedded sections of human lymph node using Mouse Anti-Human IL‑4 R alpha Monoclonal Antibody (Catalog # MAB230) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to plasma cells.

Cell Proliferation Induced by IL‑4 and Neutralization by Human IL‑4 R alpha 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 (0.2 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL‑4 R alpha Monoclonal Antibody (Catalog # MAB230). The ND50 is typically 3-6 ng/mL. |
