MOTS-C Research Peptide

MOTS-C is a short peptide of sixteen amino acid residues. What distinguishes it structurally from most peptides studied in the laboratory is its origin: the open reading frame encoding it lies inside the mitochondrial 12S ribosomal RNA gene (MT-RNR1), not in the nuclear genome. It is therefore classified as a mitochondrial-derived peptide.

The sequence contains two methionine residues and a tryptophan, which is analytically relevant. Methionine is susceptible to oxidation during handling and storage, and an oxidised species appears as a distinct chromatographic peak, which is one reason chromatographic separation is informative for this sequence.

Material supplied for research use is produced synthetically and is not extracted from tissue.

Published Vial Drop Labs documentation for MOTS-C research material is produced by HPLC-DAD: the report states the target peak's share of total integrated peak area, the content per vial against label claim, and identity as conforming by retention-time and UV/DAD comparison against a reference standard.

For a sequence of this length and composition, chromatographic resolution of closely related species — deletion sequences, oxidised methionine forms — is the practical purpose of the HPLC run.

A Certificate of Analysis links a submitted sample to the analytical work performed on it. Current Vial Drop Labs reports are produced by validated HPLC-DAD methodology and answer two separate questions — what the material is, and how much of it is present.

Vial Drop Labs publishes independent analytical reports for tested research materials, with available reports accessible through the Research Documentation portal against the research material and the sample identified on each report. Each analytical report applies only to the sample submitted for analysis and should not be interpreted as testing of every vial or production unit.

Not every report is publicly listed. Where no report has been published for a material, the portal shows none rather than substituting another material's, strength's or batch's results. Documentation is never averaged, combined, or extrapolated between lots.

Current reports are issued by an independent third-party analytical laboratory using validated HPLC-DAD methodology. They report chromatographic purity as area %, content per vial against label claim, and identity as conforming by retention-time and UV/DAD comparison against a reference standard. Current reports do not include mass-spectrometry results.

Vial Drop Labs makes no representation that material is pharmaceutical grade, clinical grade, sterile, safe, or approved by any regulatory authority. Published documentation states exactly what was tested, by which method, and on which date — nothing further should be inferred from it.

Material is supplied lyophilised in a sealed glass vial. General laboratory practice for lyophilised peptides applies: store sealed at -20 °C for long-term storage, protect from light, and minimise exposure to atmospheric moisture.

Allow a cold sealed vial to equilibrate to ambient temperature before opening so that atmospheric moisture does not condense onto the dry cake. Lyophilised peptide material is hygroscopic, and repeated warm/cold cycling of an opened vial is the most common cause of avoidable degradation in a laboratory setting.

Handle as an uncharacterised laboratory chemical using standard laboratory protective equipment and institutional handling procedures.

This material is supplied strictly as a laboratory research chemical. It is not a drug, supplement, cosmetic, food or medical device, and it is not manufactured, labelled or sold for human or animal use of any kind.

Vial Drop Labs does not provide, and cannot provide, dosing, administration, preparation-for-use, therapeutic or clinical guidance. Published information is limited to chemical identity, laboratory handling and analytical documentation.
