Anti-Myostatin Propeptide

Myostatin (GDF-8) is expressed uniquely in human skeletal muscle as a 12kD mature glycoprotein consisting of 113 amino acid residues and secreted into plasma. Myostatin is a member of the transforming growth factor beta superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass. Studies have shown that myostatin could play an important role in cardiac development and physiology. In serum, myostatin circulates as part of a latent complex containing myostatin propeptide and/or follistatin-related gene. The myostatin propeptide is known to bind and inhibit myostatin in vitro. This interaction is relevant in vivo, with a majority (>70%) of myostatin in serum bound to its propeptide. The myostatin propeptide is negative regulator of myostatin in vivo. Applications: Suitable for use in ELISA and Western Blot. Other applications have not been tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher.
