⚠️ Laboratory Research Notice
All peptide compounds discussed in this guide are strictly intended for in vitro cellular research, analytical laboratory testing, and chemical evaluation. They are not approved for human or animal consumption, diagnostic use, or therapeutic applications.
Finding authentic MOTS-c for sale requires verifying that the synthetic sequence includes both methionine residues (Met-1 and Met-6) in un-oxidized form. Methionine sulfur atoms are prone to oxidation during synthesis and cleavage, forming methionine sulfoxide, which alters tertiary structure and impairs biological activity.
For laboratory scientists, demanding third-party HPLC and Mass Spectrometry validation prevents experimental failure caused by oxidized peptide sequences.
Preserving Methionine Residues During Synthesis
A rigorous Certificate of Analysis for MOTS-c must confirm:
– Mass Spectrometry: Exact mass of 2174.6 Da. A secondary peak at +16 Da or +32 Da indicates methionine oxidation (+16 = one oxidized sulfur; +32 = both oxidized).
– HPLC Purity: A single sharp peak with ≥ 99.0% purity.
– Sterile Filtration: Endotoxin testing confirming < 10 EU/mg for non-toxic cellular culture assays.
– Mass Spectrometry: Exact mass of 2174.6 Da. A secondary peak at +16 Da or +32 Da indicates methionine oxidation (+16 = one oxidized sulfur; +32 = both oxidized).
– HPLC Purity: A single sharp peak with ≥ 99.0% purity.
– Sterile Filtration: Endotoxin testing confirming < 10 EU/mg for non-toxic cellular culture assays.

Frequently Asked Questions
❓ Does MOTS-c require special handling compared to other peptides?
Because of its two methionine residues, it is slightly more sensitive to oxidation. Keep vials sealed until immediate reconstitution.
❓ How long does unmixed MOTS-c remain viable in the freezer?
Up to 36 months when stored at -20°C.
❓ Where can I learn about safe ordering?
