Introduction
Myostatin (GDF-8), a member of the TGFbeta superfamily, is a potent and specific negative regulator of skeletal muscle mass. 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.
Description
Recombinant Human Myostatin Propeptide is a 27.8kDa protein containing 244 amino acid residues of the human Myostatin Propeptide.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered white lyophilized (freeze-dried) powder.
Formulation
Lyophilized with no additives.
Solubility
It is recommended to reconstitute the lyophilized Myostatin Propeptide in sterile 20mM HCl at 0.1mg/ml, which can then be further diluted to other aqueous solutions.
Stability
Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time.
Purity
Greater than 95.0% as determined by SDS-PAGE.
