MOTS-C Handling Guide: Common Mistakes to Avoid
Most handling advice for research peptides is written generically. The practices below are the ones that specifically matter for MOTS-C — including the mistakes it is unusually easy to make with this compound.
In plain English
Amber vials or foil, treated as a requirement rather than a nicety. Minimise vial openings. Use low-binding labware for dilute solutions.
What MOTS-C actually is
MOTS-c has one of the more surprising origins in this catalogue: its instructions are written not in the DNA of the cell nucleus but inside the separate, much smaller genome carried by mitochondria — the structures that produce most of a cell's energy. It is studied as a signal they send out to the rest of the cell.
Supplied for laboratory research use only — not for human or animal use.

Bench practices for MOTS-C
- Use amber vials or wrap in foil; treat light protection as mandatory rather than precautionary.
- Minimise vial openings — headspace oxygen is the practical driver of oxidation.
- Use low-bind labware for dilute working solutions.
The chemistry behind these practices
- Methionine oxidation to the sulfoxide (+16 Da), and MOTS-c carries methionine at the N-terminus and internally.
- Tryptophan photo-oxidation, producing a mixture of oxidised species detectable as multiple +16/+32 Da satellites.
- Adsorption to surfaces at dilute concentration, from the cationic character.
