Source: Human cells derived

Structure: Glycosylated monomer

Purity: >95% by SDS-PAGE

Endotoxin Level: <0.5EU/ug

Molecular Weight: 30kDa

Formulation: Lyophilized from a 0.2μm filtered solution in PBS without carrier protein


Activity Assay

The activity was measured by its ability to stimulate the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).



Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile PBS containing 0.1% endotoxin-free recombinant human serum albumin.


Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -80°C under sterile conditions after reconstitution.


Protein Description

Oncostatin M (OSM) is a 30 kDa secreted cytokine belonging to the Interleukin 6 family. OSM inhibits the proliferation of a number of tumor cell lines. It also stimulates proliferation of AIDS-KS cells. It regulates cytokine production, including IL-6, G-CSF and GM-CSF from endothelial cells. OSM plays crucial roles in inflammation, neuroprotection, hematopoiesis, metabolism and development.
