Structural Context
MOTS-C is a 16-amino-acid synthetic polypeptide. The sequence contains multiple basic residues (Arginine and Lysine) which confer a high calculated isoelectric point, while the presence of aromatic residues (Tryptophan, Tyrosine, and Phenylalanine) provides distinctive UV absorbance characteristics. The incorporation of a methionine residue at positions 1 and 5 introduces oxidation-susceptible sites useful for stability profiling. The proline residue at position 12 introduces conformational constraint to the peptide backbone. This defined 16-residue structure makes the peptide suitable for analytical method development, chromatographic reference studies, and stability assessments in controlled laboratory environments.
Handling and Storage
The peptide is supplied in lyophilized (freeze-dried) powder form. For optimal stability, storage at or below -20°C is recommended. Protect from repeated freeze-thaw cycles and prolonged exposure to light, heat, and moisture.
Research Applications
This product is manufactured and supplied as a chemical reference standard for in-vitro laboratory research applications including analytical method development, chromatographic reference studies, stability assessments, and polarity profiling in controlled laboratory environments.
