Recombinant Human Oncostatin M
Induced proliferation of TF-1 cells assay for Human Oncostatin M. Cell proliferation was measured to calculate the ED50, which is as expected less than 4 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human Oncostatin M has a predicted Mw of 23.8 kDa.

Oncostatin M (OSM) is a cytokine that is produced by macrophages, dendritic cells, and T lymphocytes during inflammatory events. The Type-I and Type-II OSM receptors are located on the cell surface of endothelial and tumor cells, contain the glycoprotein 130 (gp130) subunit, and activate the JAK/STAT signaling pathway. OSM functions to inhibit tumor cell proliferation, induce liver stem cell maturation, regulate cytokine production during hematopoiesis and inflammation, stimulate bone formation, and promote nervous system development.Activity Assay
Human Oncostatin M is fully biologically active when compared to standard. The activity is determined by the ability to induce TF-1 cells proliferation and it is typically less than 4 ng/ml. This corresponds to an expected specific activity of 2.5 x 105 units/mg.AA Sequence
