MOTS-c reconstitution and storage
MOTS-c's numbers in one place: the mitochondrial-derived 16-residue peptide, its mass, vial size, concentration table and what its report should show.
Published September 4, 2026
MOTS-c is encoded inside the mitochondrial genome rather than the nuclear one, which is what makes it interesting and what its name records.

A 10 mg vial is about 4.6 micromoles. The MOTS-c calculator has the weight preset.
Handling
Water down the inside wall, swirl, never shake. Freezer for the dry powder, fridge short term and once in solution. Storage guide.

SS-31 is a four-residue mitochondrial-targeting peptide at 639.79 g/mol, also known as elamipretide. NAD+ is not a peptide at all but a coenzyme at 663.43 g/mol, studied in the same metabolic area. Different molecules, adjacent questions.
Every MOTS-c vial from pepuro ships free, from our Calgary, Toronto and Vancouver distribution centers, the same business day your e-Transfer clears, with a QR code on the vial that opens its independent, third-party lab report.

Frequently asked questions
What is the molecular weight of MOTS-c?
+
2174.62 g/mol, formula C101H152N28O22S2. Its sequence is MRWQEMGYIFYPRKLR, 16 residues.
What does mitochondrial-derived mean?
+
MOTS-c is encoded within the mitochondrial 12S ribosomal RNA gene rather than in nuclear DNA. That is unusual, and it is why the peptide is studied as a signalling molecule between the mitochondria and the rest of the cell.
How much water do I add to a 10 mg MOTS-c vial?
+
1 mL gives 10 mg/mL, 2 mL gives 5 mg/mL, 5 mL gives 2 mg/mL. At 2,174.62 g/mol, 10 mg is about 4.6 micromoles.
How does it compare with SS-31?
+
Both are studied in mitochondrial research but they are very different molecules. SS-31 is a four-residue peptide at 639.79 g/mol; MOTS-c is 16 residues at 2,174.62.
