Function
Growth regulator. Inhibits the proliferation of a number of tumor cell lines. Stimulates proliferation of AIDS-KS cells. It regulates cytokine production, including IL-6, G-CSF and GM-CSF from endothelial cells. Uses both type I OSM receptor (heterodimers composed of LIFR and IL6ST) and type II OSM receptor (heterodimers composed of OSMR and IL6ST). Involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration (By similarity).

Notes
Human Oncostatin M/OSM ELISA Kit (ab215543) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Oncostatin M/OSM protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Oncostatin M/OSM with 2.1 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Oncostatin M is a 28-kDa pleiotropic cytokine of the IL-6 family that is a product of activated T lymphocytes, monocytes, neutrophils, and some tumor cells including breast cancer epithelial cells. Oncostatin M participates in a number of developmental, skeletal and immunological processes. Oncostatin M inhibits the proliferation of a number of tumor cell lines. It stimulates proliferation of AIDS-KS cells. Oncostatin M regulates cytokine production, including IL-6, G-CSF and GM-CSF from endothelial cells. It uses both type I OSM receptor (heterodimers composed of LIPR and IL6ST) and type II OSM receptor (heterodimers composed of OSMR and IL6ST). Oncostatin M is involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration.
Supplementary info

- Activity summary
Oncostatin M (OSM) also known as Oncostatin M protein or OSM protein is a cytokine with significant roles in inflammation and hematopoiesis. This protein weighs around 28 kDa and is expressed mainly in activated T cells monocytes and macrophages. It interacts with specific receptors on the cell surface to transmit signals that regulate cell growth and function. Oncostatin M is part of the interleukin-6 (IL-6) family contributing to various cellular processes.
- Biological function summary
Oncostatin M modulates a range of cellular activities including cell proliferation differentiation and apoptosis. This cytokine affects diverse cell types such as fibroblasts endothelial cells and epithelial cells showing particular influence in processes like tissue remodeling and immune response. It acts as a monomer and does not need assembly into a larger complex to exert its function. Its ability to trigger gene expression differentiates it from other closely related cytokines.
- Pathways
Oncostatin M involves itself in significant pathways like the JAK/STAT signaling pathway and the MAPK pathway. Through these pathways it promotes signal transduction essential for immune regulation and cellular response to external stimuli. OSM interacts with proteins like the gp130 receptor a common signaling component for cytokine receptors in its family and influences downstream effectors involved in these pathways.
- Associated diseases and disorders
Oncostatin M associates itself with inflammatory diseases such as rheumatoid arthritis and cardiovascular disorders. Its elevated levels in pathological conditions highlight its role in exacerbating inflammatory responses. In rheumatoid arthritis OSM promotes synovial inflammation while in cardiovascular diseases it may influence vascular remodeling. Connections to inflammatory proteins such as IL-6 further highlight its part in driving disease pathogenesis making it an intriguing target for therapeutic intervention.

Sandwich ELISA - Human Oncostatin M/OSM ELISA Kit (ab215543)
Example of human Oncostatin M standard curve.
Background-subtracted data values (mean +/- SD) are graphed.
Sandwich ELISA - Human Oncostatin M/OSM ELISA Kit (ab215543)
Interpolated concentrations of native Oncostatin M in human cell culture supernatant samples.
The concentrations of Oncostatin M were measured in duplicates, interpolated from the Oncostatin M standard curves and corrected for sample dilution. Undiluted samples are as follows: stimulated U937 supernatant 50% and stimulated PBMC supernatant 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean (target) concentration was determined to be 362.5 pg/mL in neat stimulated U937 supernatant and 2800 pg/mL in neat stimulated PBMC supernatant.
Sandwich ELISA - Human Oncostatin M/OSM ELISA Kit (ab215543)
Interpolated concentrations of spike Oncostatin M in human serum and plasma samples.
The concentrations of Oncostatin M were measured in duplicates, interpolated from the Oncostatin M standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 100%, plasma (citrate) 100%, plasma (heparin) 100% and plasma (EDTA) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
Sandwich ELISA - Human Oncostatin M/OSM ELISA Kit (ab215543)
Comparison of Oncostatin M in unstimulated and TPA stimulated human U937 cell supernatants.
U937 cells were cultured in the absence or presence of 10 ng/mL TPA for 72 hours. The concentrations of Oncostatin M were measured in 50% supernatant samples in duplicates and interpolated from the IL-4 standard curve. The interpolated values are plotted (mean +/- SD, n=2). The mean Oncostatin M concentration was determined to be 363 pg/mL in neat TPA stimulated U937 cell supernatant, 24.9 pg/mL in neat unstimulated supernatants and undetectable in media (not shown).
Sandwich ELISA - Human Oncostatin M/OSM ELISA Kit (ab215543)
Comparison of Oncostatin M in unstimulated and PHA-M stimulated human PBMC cell supernatants.
Human PBMC cells were cultured in the absence or presence of 1.5% PHA-M for 46 hours. The concentrations of Oncostatin M were measured in 25% supernatant samples in duplicates and interpolated from the Oncostatin M standard curve. The interpolated values are plotted (mean +/- SD, n=2). The mean Oncostatin M concentration was determined to be 2800 pg/mL in neat PHA-M stimulated PBMC cell supernatant, 96 pg/mL in neat unstimulated supernatants and undetectable in media (not shown).
