Technical Data
Myostatin Fusion Protein, Recombinant, Human, E. coli (Lyophilized) (Growth Differentiation Factor 8, MSTN, gdf8)
Molecular Biology Storage: -20CShipping: Blue Ice
Myostatin (GDF-8) is expressed uniquely in human skeletal muscle as a 12kD mature glycoprotein consisting of 113aa 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.

Total 152AA. M.W. 16.7kD (calculated). N-terminal His-tag and spacer (43AA highlighted). The AA sequence of the human myostatin part of the fusion protein is corresponding to the UniProtKB/Swiss-Prot entry O14793.

Recombinant Human Myostatin part of the fusion protein is corresponding to amino acid sequence of the human Myostatin (Acc. No. AF019627, R263-S376).

Suitable for use in ELISA and Western Blot. Other applications not tested.
