一般描?/p>
Oncostatin M (OSM) is produced by activated T cells, monocytes and Kaposi′s sarcoma cells. OSM shares several structural and functional characteristics with leukemia inhibitory factor (LIF), interleukin-6 (IL-6), and ciliary neurotrophic factor (CNTF). The human OSM gene encodes for a 252 amino acid polypeptide, containing 25 amino acid signal sequence for secretion and a 227 precursor protein. Proteolytic processing of this precursor removes an 18 amino acid C-terminal peptide and generates the mature OSM form. Human OSM is active on murine cells. Recombinant human Oncostatin M is a 23.9kDa protein, containing 209 amino acid residues.
生化/生理作用
Oncostatin M (OSM) is a growth and differentiation factor that participates in the regulation of neurogenesis, osteogenesis and hematopoiesis. It can exert both stimulatory and inhibitory effects on cell proliferation. OSM 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. interleukin-6 (IL-6), granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte-colony-stimulating factor (G-CSF)] from endothelial cells, and enhances the expression of low-density lipoprotein receptor in hepatoma cells.

外形
Lyophilized from 10 mM Sodium Citrate, pH 4.0.
重悬
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8 for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20 to -80?
