Recombinant Mouse IL-34 protein(N-His)(active) Sizes: 20μg, 100μg Catalogue Numbers: PKSM041479-20, PKSM041479-100 Citations, Manuals and MSDS Available upon request. Abbreviation: IL-34 Target Symptom: Za11 Target Species: Mouse Expression Host: E.coli Application: Cell culture Fusion Tag: N-His UNIProt ID: Q8R1R4 Accession: Q8R1R4 Background: Interleukin-34 (IL-34) is a protein that promotes the proliferation, survival and differentiation of monocytes and macrophages. It also promotes the release of proinflammatory chemokines, and thereby plays an important role in innate immunity and in inflammatory processes. IL-34 plays an important role in the regulation of osteoclast proliferation and differentiation, and in the regulation of bone resorption. Signaling via CSF1R and its downstream effectors stimulates phosphorylation of MAPK1/ERK2 AND MAPK3/ERK1. Activity: Measure by its ability to induce proliferation in NFS-60 cells. The ED50 for this effect is < 30 ng/mL. The specific activity of recombinant mouse IL-34 is > 3. 3 x 10⁴IU/mg.
