Powder Description
Myostatin, a negative regulator of skeletal muscle growth, is a promising target for treating muscle atrophic disorders. A novel peptide myostatin inhibitory peptide 3d displayed an IC50 value of 0.32 μM, which is 11 times more potent than peptide(WRQNTRYSRIEAIKIQILSKLRL-amide). The peptide 3d would have the potential to be a promising drug lead to develop better peptidomimetics. Storage Guidelines
Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides References

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.
Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.
Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.
In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
