Description
Background:
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
Source
E. coli
Molecular Weight
The predicted molecular weight of Recombinant Mouse OSM is Mr 21 kDa.
State of Matter
Lyophilized
Formulation
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Purity
>97% by SDS-PAGE and analyzed by silver stain.
Storage and Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
Endotoxin
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Mouse OSM was measured in a cell proliferation assay using NIH/3T3 mouse embryonic fibroblasts. The expected ED50= 0.25-1.0 ng/ml.
Each investigator should determine their own optimal working dilution for specific applications.
