MOTS-c is a 16-amino-acid peptide encoded by a short open reading frame (sORF) within the mitochondrial 12S rRNA. MOTS-c, which is a contraction of mitochondrial open reading frame of the 12S rRNA-c, regulates insulin sensitivity and metabolic homeostasis with its primary target organ being skeletal muscle. The cellular action of MOTS-c is to inhibit the folate cycle and its tethered de novo purine biosynthesis, leading to activation of AMP-activated protein kinase (AMPK), a central regulator of energy homeostasis. In mouse models, MOTS-c treatment prevents age dependent and high fat diet-induced insulin resistance, as well as diet induced obesity.

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

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.
