Recombinant Human Oncostatin M

DESCRIPTION CATALOG # SIZE PRICE
Recombinant Human Oncostatin M CRP0893 1mg Please Inquiry
Product Detail
Cat
CRP0893
Product Overview
Recombinant Human Oncostatin M produced in E. coli is a single non-glycosylated polypeptide chain containing 227 amino acids and having a molecular mass of 26kDa.
Specificity
Fully biologically active when compared to the standard. The ED50 as determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is < 2 ng/ml, corresponding to a specific activity of > 5×105 units/mg.
Endotoxin
Less than 1EU/mg of rHuOSM as determined by LAL method.
Purity
>95% by SDS-PAGE and HPLC analyses.
Storage
This lyophilized preparation is stable for several weeks at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤20°C. Further dilutions should be made in appropriate buffered solution

Background
Antigen Description
Oncostatin M (OSM) is a growth and differentiation factor that participates in the regulation of neurogenesis, osteogenesis and hematopoiesis. Produced by activated T cells, monocytes and Kaposi's sarcoma cells, OSH can exert both stimulatory and inhibitory effects on cell proliferation. It stimulates the proliferation of fibroblasts, smooth muscle cells and Kaposi's sarcoma cells, but, inhibits the growth of some normal and tumor cell lines. It also promotes cytokine release (e.g. IL-6, GM-CSF and G-CSF) from endothelial cells, and enhances the expression of low-density lipoprotein receptor in hepatoma cells. OSM share several structural and functional characteristics with LIF, IL-6, and CNTF. Human OSM is active on murine cells.
