Product Overview
This rabbit polyclonal antibody targets oncostatin-M (gene Osm) in mouse and rat samples and is validated for Western blot and ELISA. The predicted molecular weight is 27.1 kDa, and the supplier reports an observed band at about 27 kDa.
Oncostatin M (OSM) is an IL-6 family cytokine produced mainly by activated T cells, monocytes and neutrophils. It signals through gp130 paired with OSMR or LIFR to activate JAK–STAT pathways, and it is studied in inflammation, liver regeneration, fibrosis, bone remodeling and hematopoiesis.

Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant rat Osm fragment (Glu55–Asp158), expressed in E. coli. Sequence identity with the human and mouse orthologs: 46% and 71.2%, respectively.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes oncostatin-M as a secreted protein. Tissue expression noted by UniProt (rat): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
