Technical Data
Myostatin Fusion Protein, Recombinant, Human (Lyophilized) (Growth Differentiation Factor 8, MSTN, gdf8)
Molecular Biology Storage: -20CShipping: Blue Ice
Myostatin is a TGF-beta family member that acts as an inhibitor of skeletal muscle growth. This muscle-specific cytokine interacts with Activin type I and type II receptors, and suppresses myoblast proliferation by arresting cell-cycle in the G1 phase. Suppression of myostatin activity facilitates muscle formation and may be useful in reducing and/or preventing adiposity and type-2 diabetes. Myostatin activity can be blocked by the Activin-binding protein Follistatin, and by the propeptide of Myostatin.

Recombinant Human myostatin is a 25kD protein consisting of two identical 109 amino acid polypeptides linked by a single disulfide bond.

Biological Activity:
Determined by its ability to inhibit the proliferation of MPC-11 cells. The expected ED50 for this effect is 17-25ng/ml.
