Mature myostatin is obtained by proteolytic processing of a biologically-inactive precursor protein, which contains an N-terminal propeptide of 243 amino acid residues.  Myostatin-Propeptide exhibits high binding affinity for myostatin, and has been shown to be a potent inhibitor of myostatin.  Over-expression of myostatin-propeptide in mice resulted in large increases (up to 200%) in skeletal muscle mass, similar to those observed in myostatin knockout mice.  Recombinant Human Myostatin-Propeptide is a 27.8 kDa protein consisting of 244 amino acid residues.

Purity: ≥ 98% by SDS-PAGE gel and HPLC analyses.

Biological Activity: Determined by its ability to neutralize the Myostatin inhibitory effect of murine MPC-11 cells. The expected ED₅₀ is 0.01–0.04 μg/ml in the presence of 50 ng/ml Myostatin.
