MOTS-C

You can buy MOTS-C from Peptide Lab as a laboratory-verified research peptide with 99.4% purity, for research purposes only. MOTS-C is a unique peptide: it is one of the so-called mitochondrial-derived peptides, encoded by the DNA of the mitochondria themselves. It is a growing area of interest within metabolic and longevity research and is supplied as a lyophilised powder, 40 mg per vial.

Who is MOTS-C intended for?

MOTS-c is intended for researchers and laboratories studying mitochondrial function, energy metabolism and ageing. Related compounds include NAD+ and SS-31; see also the Fat Loss & Metabolism category.

MOTS-c (Mitochondrial ORF of the 12S rRNA type-c) is a short peptide encoded by mitochondrial DNA. This is unusual: most peptides are encoded by the DNA in the cell nucleus.

Mechanism of action under investigation

Research is being carried out into MOTS-c in relation to energy metabolism and communication between the mitochondria and the rest of the cell. It is often described as a molecule involved in the way cells adapt to metabolic stress, for example during exercise.

These mechanisms are based on preclinical research and describe the research context; they do not represent proven effects in humans.

The fact that MOTS-c is encoded by mitochondrial DNA places it in a small, distinctive family of molecules. Researchers view mitochondrial-derived peptides as evidence that mitochondria are not only powerhouses but can also send signals to the rest of the cell. In preclinical models, research is focusing, amongst other things, on their role in exercise and metabolic flexibility, always within a strict research framework.

The discovery of such peptides has shifted the view of mitochondria from being merely energy producers to that of active participants in cell communication.

MOTS-c was discovered relatively recently and belongs to a new class: mitochondrial-derived peptides. Research is still at an early stage, but its unique origin makes it a popular subject of study within biogerontology.

• Research focus: mitochondrial energy metabolism.
• Research focus: metabolic adaptation and exercise (preclinical).
• Research focus: communication between mitochondria and the cell nucleus.

Status of human research

MOTS-c has not been authorised as a medicinal product and research into it is predominantly pre-clinical; human clinical outcomes have not been established. As a research material, MOTS-c is intended solely for laboratory and research purposes. In a relatively new field of research, a pure, well-documented starting material is particularly important for reliable results.

As this is a relatively new field of research, new publications appear regularly and our understanding is still evolving. For researchers, this means that reproducibility and the use of pure starting materials are of particular importance: only in this way can results be properly compared across laboratories.

For comparable studies, record the method, cell type and storage conditions for each experiment.

MOTS-c is supplied as a lyophilised powder and reconstituted in the laboratory using bacteriostatic water. The steps below describe only the laboratory procedures for research purposes.

1. 1Allow the vial and the bacteriostatic water to reach room temperature.
2. 2Wipe the rubber stoppers of both vials with an alcohol wipe.
3. 3Allow the bacteriostatic water to run slowly down the side of the vial; do not direct it straight onto the powder.
4. 4Gently swirl the vial until everything has dissolved; do not shake.
5. 5Store the solution in the fridge and label it with the date and batch number.

Items such as bacteriostatic water, insulin syringes and alcohol wipes can be found under ‘Lab & Accessories’. This is a laboratory instruction and does not constitute dosage advice for consumption.

Combining approaches in research

In metabolic and longevity research, MOTS-c is sometimes studied alongside molecules such as NAD+, as both are involved in cellular energy metabolism. Document each compound separately, stating its purity and batch number.

Working with a larger volume of powder

With a 40 mg vial, it is important to calculate the reconstitution volume accurately in order to achieve the desired concentration; make a note of this calculation in your experiment.

Store MOTS-c in powder form in a cool, dark place to ensure maximum stability.

Practical storage tips

• Powder form: freezer (-20 °C) for long-term storage; fridge (2–8 °C) for short-term storage.
• After reconstitution: store refrigerated (2–8 °C) and use within a few weeks.
• Avoid direct light, heat and repeated temperature changes.
• Write the reconstitution date and batch number on the vial.

Careful storage preserves the purity of the research material.

Consistent, cold storage ensures reliable and reproducible measurement results across experiments.
