Mouse IL-7 Antibody

(6 citations)   
  • Species Reactivity
    Mouse
  • Specificity
    Detects mouse IL-7 in ELISAs and Western blots. In sandwich immunoassays, approximately 20% cross-reactivity with recombinant rat IL-7 is observed, and less than 0.1% cross‑reactivity with recombinant human IL-7 is observed. Neutralizes the biological activity of recombinant mouse IL-7. It will not neutralize the biological activity of recombinant human IL-7.

    Measured by its ability to neutralize IL‑7-induced proliferation in PHA-activated human peripheral blood mononuclear cells (PBMC). The Neutralization Dose (ND50) is typically 0.2-0.4 µg/mL in the presence of 1.5 ng/mL Recombinant Mouse IL‑7.
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.
Data Examples
Cell Proliferation Induced by IL‑7 and Neutralization by Mouse IL‑7 Antibody. Recombinant Mouse IL‑7 (Catalog # 407-ML) stimulates proliferation in PHA-activated human peripheral blood mononuclear cells (PBMC) in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑7 (1.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF407). The ND50 is typically 0.2-0.4 µg/mL.

Background: IL-7

IL-7, previously known as pre-B-cell growth factor and lymphopoietin-1, was originally purified on the basis of its ability to promote the proliferation of precursor B‑cells. It has now been shown that IL-7 can also stimulate the proliferation of thymocytes, T cell progenitors and mature CD4 + and CD8+ T cells. IL-7 can induce the formation of lymphokine-activated killer (LAK) cells as well as the development of cytotoxic T lymphocytes (CTL). IL-7 was also shown to induce the V(D)J rearrangement of the T cell receptor beta gene in mouse fetal thymocytes. Among myeloid lineage cells, IL-7 can up-regulate the production of pro-inflammatory cytokines and stimulate the tumorocidal activity of monocytes/macrophages. IL-7 is expressed by adherent stromal cells from various tissues.

Mouse IL-7 cDNA encodes a precursor protein of 154 amino residues containing a 25 amino acid residue signal peptide. Human IL-7 has approximately 65% amino acid sequence identity with mouse IL-7 and both proteins exhibit cross-species activity.

IL-7 bioactivities are mediated by the binding of IL-7 to functional high-affinity receptor complexes. The ligand binding subunit (IL-7 R) of the IL-7 receptor complex has been cloned from human and mouse sources. In addition to the membrane-anchored form of the IL-7 receptor, a human cDNA clone that encodes a soluble form of the IL-7 R has also been isolated. The gamma  chain of the IL-2 receptor complex has been shown to be an essential component for IL-7 signal transduction. Both IL-7 R and IL-2 R gamma are members of the hematopoietin receptor superfamily. Cells known to express IL-7 receptors include pre-B cells, T cells and bone marrow cells.
