45x Ab-conjugated beads (S5P9 - human OSM Ab-bead). PN: B111437A. One vial containing 100 µL of anti-human OSM conjugated to AimPlex Bead S5P9.

25x Biotin-detection Ab (human OSM Biotin-dAb). PN: B111437B. One vial containing 100 µL of biotinylated anti-human OSM.

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 OSM.  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.

Oncostatin M (Accession P13725) is part of the IL-6 cytokine family. It is produced by activated macrophages, monocytes, T cells and dendritic cells. It is most similar to LIF in function and structure and in humans, it even binds to the LIF receptor in addition to its own. OSM may have fundamental roles regarding inflammation, liver regeneration, and cardiovascular disease. OSM can inhibit growth of solid tumors and melanomas and is identified as a specific cell growth regulator. OSM is produced by both osteocytes and osteoblasts in in mouse bone and is understood to have a role in bone formation and destruction in humans.
