Product Overview
This rabbit polyclonal antibody detects oncostatin-M (gene OSM) in human samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 28.5 kDa, and the supplier reports an observed band at about 40 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.

Samples with a confirmed band (WB): A549 cells, HUT cells, Jurkat cells, SW620 cells, MCF-7 cells.
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, 40 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.
Samples with confirmed staining (IHC): human intestinal cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human Oncostatin M fragment (Ala26–Arg220), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 47.1% and 47.6%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes oncostatin-M as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
