MOT-C

MOTS-c is unusual in a way that is easy to miss from the product listing: it is encoded inside mitochondrial DNA. Almost every peptide in a research catalog derives from a nuclear gene or is a wholly synthetic design. MOTS-c belongs to a small class of mitochondrial-derived peptides whose open reading frames sit within mitochondrial ribosomal RNA genes.

The name encodes that origin — mitochondrial open reading frame of the 12S rRNA type-c. The peptide is sixteen residues long and was first described in the scientific literature in 2015, which makes it one of the newer entries in this catalog by a wide margin.

That novelty is worth keeping in mind when reading claims about it. A decade of literature is thin ground compared with oxytocin's seventy years, and much of the mechanistic picture is still being established.

The dominant research theme is metabolic regulation, with AMP-activated protein kinase signalling as the most frequently reported pathway. Studies examine glucose handling, insulin sensitivity and exercise-associated metabolic responses, predominantly in rodent models and cell culture.

A second theme, and arguably the more conceptually interesting one, is retrograde signalling — the idea that mitochondria communicate their state to the nucleus through peptides encoded in their own genome. MOTS-c is one of the principal experimental tools in that line of work.

As with the rest of the catalog, this evidence is preclinical. No regulator has approved MOTS-c for any indication, and VaultLabs makes no claims about metabolic effects in humans.

Release is by reversed-phase HPLC against a stated purity specification with a certificate tied to the vial lot number. For a sixteen-residue peptide, truncation and deletion sequences are the related substances most worth watching for, and mass confirmation is a valuable complement where LC-MS capability exists.

Sequence verification carries extra weight for a compound this new. Reference standards are less widely distributed than for long-established peptides, fewer laboratories have an in-house comparison to fall back on, and published analytical methods are correspondingly thinner. The supplier's certificate is doing more of the work here than it would for oxytocin or glutathione, which is a reason to prefer material whose documentation is lot-linked and independently retrievable.

Store sealed lyophilised vials at 2–8 °C, protected from light and humidity, and equilibrate to room temperature before opening. After reconstitution, prepare close to the point of use and log the diluent, reconstitution date and each freeze-thaw cycle.

MOTS-c is supplied as a research reference material. It is not registered as a medicine in the United Arab Emirates and is not supplied for human or veterinary use; the research-use declaration recorded at checkout forms part of the order record.

The catalog presentation is a 10 mg lyophilised vial with lot-linked certificate retrieval through batch verification, held under controlled cold storage before UAE dispatch.
