Human IL-34 shares a sequence identity of 99.6%, 72% and 71% with chimpanzee, rat, and mouse IL-34, respectively, on the amino acid level. The IL-34 gene is syntenic in the human, chimpanzee, rat, and mouse genomes. IL-34 has no apparent consensus structural domain or motif, and does not share sequence homology with M-CSF; nevertheless, it binds to the CSFR. These two cytokines are not identical in biological activity and signal activation. IL-34 and CSF show an equivalent ability to support cell growth or survival. However, these cytokines are differing in their ability to induce the production of chemokines (MCP-1 and eotaxin-2) in primary macrophages, the morphological change in TF-1-fms cells, and the migration of J774A.1 cells. The use of monoclonal antibodies against the CSFR suggests differential domain binding of the receptor to IL-34 and CSF and as a result, different bioactivities and signal activation kinetics/strength are produced for these cytokines.Product Details

ELISA Detection - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For ELISA detection applications, a concentration range of 0.5 - 2.0 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of human IL-34 recombinant protein ranging from 5000 to 78 pg/mL are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
ELISA Detection: The biotinylated E033E8 antibody is useful as the detection antibody in a sandwich ELISA assay, when used in conjunction with the purified E0320E7 antibody (Cat. No. 361301) as the capture antibody and recombinant human IL-34 (Cat. No. 577909) as the standard.
Note: For testing human IL-34 in serum, plasma or cell culture supernatant, LEGEND MAX™ Human IL-34 ELISA Kit with Pre-coated Plates (Cat. No. 439607 & 439608) are specially developed and recommended.

IL-34 mRNA is expressed in many different tissues including: spleen, heart, brain, lung, liver, kidney, thymus, testes, ovary, small intestine, prostate, and colon
- IL-34 increases monocyte viability, induces macrophage proliferation, and synergizes with other cytokines to generate macrophages and osteoclasts from cultured progenitors. IL-34 promotes the formation of the colony forming unit-macrophage (CFU-M) in human bone marrow culture. IL-34 supports RANKL-induced osteoclastogenesis by promoting the adhesion and proliferation of osteoclast progenitors. Human IL-34 promotes osteoclast differentiation from peripheral blood mononucleated cells. In addition, systematic administration of IL-34 to mouse increases the number of CD11b+ cells and reduces bone mass. IL-1ß and TNF-Î± induce the expression of interleukin-34 mRNA in osteoblasts. IL-34 is also induced in macrophages infected with equine infectious anemia virus (EIAV).
