Chemical identity

What MOTS-C is

MOTS-c is a synthetic linear 16-residue peptide with the sequence Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg (one-letter MRWQEMGYIFYPRKLR), free N-terminus and free C-terminal acid, matching the human-encoded sequence. It contains two methionine residues, which account for the two sulfur atoms in the molecular formula C101H152N28O22S2; the molecular weight is 2174.62 g/mol (monoisotopic mass 2173.13 Da). The CAS Registry Number is 1627580-64-6, PubChem CID 146675088 and UNII A5CV6JFB78. One tryptophan and two tyrosine residues give a strong UV absorbance at 280 nm that is useful for concentration measurement. Pepta Labs lists MOTS-c in 10 mg and 40 mg vials of lyophilized powder, typically as a trifluoroacetate or acetate salt, with reported RP-HPLC purity (99.1% on the current listing) and identity confirmed by mass spectrometry. Store sealed vials at 2-8 C short term or -20 C long term; methionine residues can oxidize, so keep dry and protected from air. For laboratory research use only.

Questions

MOTS-C 10mg — common questions

What sizes of MOTS-c does Pepta Labs sell?

Two: MOTS-C 10mg (this listing) and MOTS-C 40mg. Both are the same 16-residue peptide with the same CAS number, supplied as lyophilized powder in one sealed vial; as listings they differ in the supplier-stated quantity per vial. Each size shows its own single-vial and pack prices on its own page.

What exactly is in the MOTS-C 10mg vial?

A supplier-stated 10 mg of MOTS-c as freeze-dried (lyophilized) powder in one sealed glass vial, with no liquid added. Vial fill-quantity testing is not claimed, and net peptide content (the share of the powder that is peptide rather than counter-ion and residual water) is not reported per listing. The label names the compound, quantity and research-use designation and carries no lot number.

Is MOTS-c 10mg lab tested, and how do I get the report?

Yes. Purity is measured by reversed-phase HPLC and reported as area-%, and identity is confirmed by mass spectrometry, from independent testing commissioned on a sampled production run; Pepta Labs does not test in-house. The report covers that sampled run, not an individual vial. Request it on this page or email support@peptalabs.com with the name MOTS-C 10mg, before you order if you want to see it first.

Is MOTS-c 10mg a TFA or acetate salt?

This listing does not state which counter-ion is in the current production run; MOTS-c is typically supplied as a trifluoroacetate (TFA) or acetate salt, the counter-ion left from synthesis and purification. The counter-ion adds mass to the powder without being peptide, which is why a supplier-stated quantity can differ from net peptide content. To ask about the current run, request the report on this page or email support@peptalabs.com. The Pepta Labs Learn guide How Net Peptide Content Is Determined explains counter-ion and water in detail.

How should sealed MOTS-c powder be stored?

Keep the sealed vial at 2-8 °C for short periods or at -20 °C for long-term storage, dry and away from light. MOTS-c has two methionine residues that can oxidize on contact with air and moisture, so leave the vial closed until it is needed and let a cold vial reach room temperature before opening to avoid condensation. The Learn guide on storage temperature and handling of lyophilized research peptides covers this in more depth.

What does MOTS-C 10mg cost?

MOTS-C 10mg starts at $41.60 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. MOTS-C 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What is the sequence and length of MOTS-c?

MOTS-c is a 16-residue linear peptide, MRWQEMGYIFYPRKLR, with free N- and C-termini. Its formula is C101H152N28O22S2 and molecular weight 2174.62 g/mol; the two sulfur atoms come from its two methionine residues.

Why does a mass spectrum of MOTS-c sometimes show a +16 Da peak?

Each methionine can oxidize to methionine sulfoxide, adding 16 Da per oxidized residue (+16 or +32 Da total). Keeping the lyophilized powder dry, cold and protected from air limits this, and the analytical report shows the observed mass.

What does the CAS number 1627580-64-6 identify?

It is the CAS Registry Number for the human MOTS-c 16-residue sequence as the free peptide (PubChem CID 146675088, UNII A5CV6JFB78), independent of whether the material is supplied as a trifluoroacetate or acetate salt.
