25x Biotin-detection Ab (human IL-34 Biotin-dAb). PN: B111422B. One vial containing 100 µL of biotinylated anti-human IL-34.

Lyophilized Standard Mix-Human Group 3 Panel B, 12-Plex. PN: HG3012B. One vial containing lyophilized recombinant human IL-9, IL-15, IL-16, IL-17C, IL-23p19, IL-24, IL-27, IL-31, IL-32, IL-34, OSM, and SCF.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human IL-34  Can be multiplexed with other analytes in Human Group 3.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Interleukin 34 (Accession Q6ZMJ4) is a second ligand for CSF-1R. As an interleukin, IL-34 shares some functions with colony-stimulating factor-1. In humans, IL-34 is expressed by mRNA primarily in the spleen and is involved in the proliferation of myeloid cells, macrophage differentiation, and osteoclastogenesis. In mice with IL-34 deficiency, Langerhans cells and microglia were reduced. Overexpression of IL-34 is associated with rheumatoid arthritis, inflammatory bowel disease, and Sjogren’s syndrome.
