    Asn21-Pro242
    Accession # Q6ZMJ4
  • Formulation
    Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
  • Endotoxin Level
    <1.0 EU per 1 μg of the antibody by the LAL method.
  • Label

Applications
  •  
    Recommended
    Concentration
    Sample
  • CyTOF-ready
    Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
  • Intracellular Staining by Flow Cytometry
    2.5 µg/106 cells
    Human IL-34 transfected NS0 cells fixed with paraforaldehyde and permeabilized with saponin
  • Neutralization
    Measured by its ability to neutralize IL‑34-induced proliferation in human peripheral blood monocytes. Lin, H. et al. (2008) Science 320:807. The Neutralization Dose (ND50) is typically 0.01-0.05 µg/mL in the presence of 10 ng/mL Recombinant Human IL‑34.
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‑34 and Neutralization by Human IL‑34 Antibody. Recombinant Human IL‑34 (Catalog # 5265-IL) stimulates proliferation in human peripheral blood monocytes in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL‑34 (10 ng/mL) is neutralized (green line) by increasing concentrations of Human IL‑34 Monoclonal Antibody (Catalog # MAB5265). The ND50 is typically 0.01-0.05 µg/mL.

Background: IL-34

Interleukin 34 (IL-34; also known as uncharacterized protein C16orf77) is secreted as a homodimer consisting of 39 kDa monomers (1). It belongs to no known cytokine family. Human IL-34 is synthesized as a 242 amino acid (aa) precursor that contains a 20 aa signal sequence and a 222 aa mature chain. The mature chain contains one potential site of N-linked glycosylation. Human IL-34 is 71% identical to mouse IL-34 on the amino acid level (1). IL-34 is expressed in various tissues, including the heart, brain, liver, kidney, spleen, thymus, testes, ovary, small intestine, prostate, and colon, and is most abundant in the spleen (1). The receptor for IL-34 is colony-stimulating factor 1 receptor (CSF-1R) (1). IL-34 stimulates monocyte proliferation (1). In functional studies, IL-34, like CSF-1, the other ligand for CSF-1R, stimulated phosphorylation of extracellular signal-regulated kinase-1 and -2 (ERK1/2) in human monocytes (1). In addition, IL-34 promoted the formation of the colony-forming unit-macrophage (CFU-M), a macrophage progenitor, in human bone marrow cultures (1).
