Anti-Human Oncostatin M

Purified Recombinant Human Oncostatin M (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Next Day Ambient

CyTOF-ready: Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
Neutralization: Measured by its ability to neutralize Oncostatin M/OSM-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND₅₀) is typically 0.02‑0.04 µg/mL in the presence of 2 ng/mL Recombinant Human Oncostatin M/OSM.

Rabbit Anti-Human Oncostatin M recognizes Human Oncostatin M . This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Oncostatin M (OSM) is a pleitropic cytokine produced by activated T lymphocytes and monocytes that is structurally and functionally related to the subfamily of cytokines known as the IL-6-type cytokine family.¹ OSM either inhibits or enhances the growth of cells depending on cell type. It inhibits proliferation of skeletal muscle cells by blocking cell cycle progression from G(1) to S phase.² OSM is also a key mediator for proliferation and anti-apoptosis of hepatocytes which suggests that OSM gene therapy is useful, as preventive and curative means, for the treatment of patients with liver damage.³
