MOTS-c frequently asked questions

MOTS-c is a 16-residue mitochondrial-derived peptide. MOTS-c Research Supply supplies it as a lyophilized powder in 10 mg, 40 mg vials, with an independent certificate of analysis for every lot.

MOTS-c research material is MOTS-c supplied for laboratory research, sold by lot, with each lot's identity, purity and net content documented by an independent laboratory in a published certificate of analysis.

The molecular formula is C101H152N28O22S2 and the average molecular weight is 2174.62 g/mol. The peptide has 16 residues.

Store sealed, dry and protected from light at the temperature stated on the vial label. Allow a cold vial to reach room temperature before opening.

That the certificate names MOTS-c, the HPLC purity against the stated specification, the identity method, the measured net content, and that the lot number on your vial matches a published lot. All of these are on this site.

Choose a size on the MOTS-c page at Klow.bio (https://klow.bio/product/mots-c/) and check out there. Then match your vial's lot number on the verify page here.

MOTS-c is analyzed with complementary methods: HPLC-UV for purity, HPLC-RTM for identity, a quantitative measurement for net content, and, where listed, LAL endotoxin and PCR microbial testing. Results are published per lot at buymotscpeptide.com/coa/.

Every lot is tested by ILS Laboratories, an independent third-party analytical laboratory. MOTS-c Research Supply does not test its own material for published certificates.

Current lots report HPLC-UV purity 99.90%, against a stated release specification of ≥95%. The most recent result is 99.90% for lot KB-44745.

By HPLC retention-time comparison with a reference standard (HPLC-RTM), performed by ILS Laboratories on every lot. The laboratory runs the sample and a reference standard of the named compound under the same HPLC conditions; identity is confirmed when the main peak elutes at the reference standard’s retention time.

Endotoxin and microbial testing are reported per lot. Every lot page in the COA archive states whether those tests were performed.

HPLC (high-performance liquid chromatography) separates a sample's components so each appears as a peak. The purity percentage is the main peak's share of all UV-detected peak area. It does not confirm identity (the separate HPLC-RTM test does) or measure the amount of peptide in the vial (net content does).

A MOTS-c certificate of analysis is the testing laboratory's report for one lot: the lot number, test dates, methods and results for purity, identity and net content. MOTS-c Research Supply publishes every lot's COA as a readable page at buymotscpeptide.com/coa/.

Find the lot number printed on your vial label and enter it at buymotscpeptide.com/verify/, or open that lot in the COA archive at buymotscpeptide.com/coa/.

Go to portal.ils-lab.com (or scan the QR code on the certificate) and enter the lot's verification access code, listed on its lot page, to view the laboratory's own copy of the certificate.

Net content is the laboratory's measurement of peptide in the tested vial. Current lots measured 10.71 mg in a 10 mg vial.
